Pimp Your Ride By Modifying Spark Plugs

reading spark plugs
If you really want to perform some car modification, the best thing is to first take care of your engine performance because car modification is not only about changing your car body kits and installing some sub woofers to add a groove in your sound. No car modification is completed if the car's performance is not state of the art. For this purpose, you may get many advice. I would specifically refer to the car's spark plugs and their impact on engine performance and how you can do some modifications either by some spark plugs replacement or spark plug gapping or choose the right spark plugs for your car by assessing and reading spark plugs requirements for your car.

Before getting into details I would just peek into the spark plug's functioning or how does a spark plug work. I know many of you car enthusiasts must know the purpose of spark plugs and how does a spark plug work. So I will not go into a detail.Just a quick review.

Purpose Of A Spark Plug, How Does A Spark Plug Work?

Spark plug actually causes an ignition through its ignition coil in the internal combustion chamber of the engine which creates a small spark. Search out for internal combustion engine fundamentals for more details. This spark when unites with the air and some drops of fuel, it creates a perfect combination for a small explosion. This small explosion creates a pressure which causes the pistons in the engine's cylinders to move and eventually creates a torque to move the cam shaft and ultimately the car starts to move. As simple as that.

So the purpose of a spark plug is integral in moving a car. Obviously if the spark is of not a good quality there would be implications on the car's engine performance so to perform some car modification pertaining to spark plugs, one has to make sure that the spark plug is of good quality which produces a better spark to ensure swift movement of a car.

Now coming to the spark plug modification or replacement, let us first analyze that what effects the performance of the spark plug. The spark plug's performance is effected by following factors.

1) Wear and Tear of spark plug.
2) The gap between central and ground electrode or spark plug gapping.
3) Voltage provided to create a spark.
4) Altitude and temperature of the location.

To alter the performance or efficiency of spark plugs, one should try to alter the above factors or if he is going to perform some spark plugs replacement he should keep the above factors in mind. Now let's see how the above mentioned factors effect the efficiency of a spark plug and how you can modify or use the above mentioned factors in better performance of spark plugs and ultimately of the car.
1) Wear And Tear Of Spark Plug.

Spark plugs have to go through series of small explosions in order to be functional thus making them more prone to wear and tear. So definitely a damaged spark plug or a spark plug having a lot of carbon deposited at its tip will not perform adequately. So make sure that spark plugs are always in a good condition in order for your car as whole to be efficient or perform well. Generally a spark plug's life is about 10,000 to 20,000 miles. However some manufacturers assemble spark plugs which have two or in other words multiple ground electrodes to enhance the life of a spark plug. But it has been observed that it has some implications on fuel injection of the car.

2) Spark Plug Gapping.

This is the most important factor of spark plugs performance. However people have different views about the spark plug gapping. Some say that the more the gap, the better is the spark. Where as some say that small gap is good as it requires small amount of voltage to create the spark. Normally a spark plug requires a very high voltage of about 40,000 to 100,000 volts to cover the gap. I am open here for suggestions. Tell me if you have any suggestions regarding this topic. However if you really want to make the spark plug gapping larger or smaller you can use a very fine nosed pliers as a spark plug gapper or spark plug gap tool. To enlarge the gap, pull the ground electrodes outwards using pliers. However be extremely cautious here and make sure you do not apply pressure on the center electrode or it may damage.If you want to make the gap smaller, gently tap the ground electrode on a hard surface. You can use a feeler guage to measure the gap between center and ground electrode.

3) Voltage Provided.

As described above spark plugs need a very high amount of voltage to create a spark so use a good quality car batteries to make sure that a voltage is provided to create the spark.

4) Altitude And Temperature Of The Location.

The altitude where your car operates and the temperature in which your car operates is crucial for the performance of your spark plugs. For this reason the spark plugs have been divided into two kind which are:

a) Hot Spark Plugs:

Hot spark plugs are spark plugs in which the surface area of ceramic exhaust coating contacts less with the metal part of the spark plug thus exhausting less heat. I am saying the ceramic insulator as an exhaust because the ceramic insulator coating works as a heat exhaust. So hot spark plugs are good in low performing cars or in cold areas. Similarly they are good at high altitude areas where oxygen is less to burn the fuel.

b) Cold Spark Plugs:

These spark plugs have larger surface area of ceramic insulator coating thus exhausting more heat and keeping the spark plugs cold. You can have a look at the image of spark plugs structure for spark plug cross reference. Cold spark plugs are best for high performance engines or turbo charged engines. If you are looking forward for engine upgrades then I reckon you should also pay some consideration towards your spark plug replacement.

Above mentioned factors are helpful in assessing and reading spark plugs requirements for your car. You may have come to know how spark plug can be modified by changing spark plugs gapping as well as what spark plugs would be better for your car's specific requirements.

Try Iridium Spark Plugs For The Next Spark Plug Replacement.

Are you looking for your car's spark plug replacement because the present spark plugs have wore off? I have an advice for you. This time try embedding in your car engine, iridium spark plugs. The advent of modern technology has also effected the cars as well and have made them much more efficient.Using iridium tips in spark plugs is also one of its dimensions. Iridium spark plugs has many advantages and it can really pimp your ride. Refer to my last article on how spark plugs can pimp your ride and how you can perform spark plug replacement.

Advantages Of Having Iridium Spark Plugs.

Before acquainting you about the advantages of iridium spark plugs, I want to make one thing clear. Spark plugs don't enhance the efficiency of the car beyond its limits but instead they make it more efficient according to the car's own potential. So clear your mind from any misconceptions that its only the spark plugs that will make your crawling ride in to a super fast car.

Now coming to the advantages of iridium spark plugs, they sure are durable and strong enough as compared to other conventional platinum tipped, spark plugs. Durability of iridium spark plugs can be compared as it has a life of almost 60, 000 miles where as the conventional will give you 20,000 to 40,000 miles. Of course because of the good quality of the element, the quality of spark is improved and gives a much better spark hence improving fuel efficiency.

The best thing about the iridium spark plug is that it wears off rather slowly as compared to platinum spark plugs. The reason is of course, iridium is much more durable than its "colleague" platinum. Besides this, the melting point of iridium is much more higher than platinum. The melting point of iridium is 4450 F where as that of platinum is almost 3216 F. That's a huge difference. Furthermore, iridium is 8 times more rigid than platinum where it can endure a pressure of 160 Kpsi as compared to platinum which can stand a pressure of not more than 20 Kpsi. Because of these qualities, the iridium spark plugs wear off much slowly as compared to those conventional spark plugs so you don't have a headache of replacing your spark plugs after some years.

Learning above attributes of iridium I bet you would go for high quality iridium spark plugs the very next time you perform your car's spark plug replacement.

Car Modification - Legal Issues

In the last article we talked about Safety Mods. Now it would be appropriate to have a look at some legal issues arising due to car modification. For this purpose I would present an extract from a website which deals with and educates on the legal implications due to car modification. But before that I would like to have some words with you.

Laws enacted by law enforcing agencies are for the betterment of oneself so you must not take steps to violate these laws as it could prove lethal to you as well as civilian around you in long or short run. Now lets see what legal problems you can get into because of unlawful car modification.


Under traffic laws in most states, drivers may be given a traffic ticket for operating a vehicle that has been modified in violation of laws that regulate vehicle specifications and vehicle equipment. Examples of vehicle modifications that may result in a traffic ticket include:

* Addition of non-standard lighting (neon lights, under-vehicle lights),
* Alteration or removal of air pollution and emissions control device
* Modification of vehicle ground clearance ("lowered" or "raised" vehicles),
* Removal of mufflers and other sound-control devices, and
* Window tinting (especially tinting of windshield or driver/front passenger side windows).

An unlawfully-modified vehicle can receive a traffic ticket for a mechanical violation. In some states, citations for certain unlawful vehicle modifications are considered "fix-it" tickets or "correctable violations." In California, for example, if you are given a "fix-it" ticket by a police officer, "yes" will be checked next to "Correctable Violation", and after the problem is fixed (i.e. you remove illegal under-car lights), you must get the signature of an authorized person (i.e. a local law enforcement officer) on the "Certificate of Correction" portion of the ticket. If you are issued a "fix-it" ticket for an unlawful vehicle modification in your state, read the ticket to determine whether you can mail the proof of correction, rather than taking it to court.

If the court accepts your correction, the case will be dismissed. But, if you fail to fix the problem within a short time after you receive a "fix-it" ticket, you will need to pay the fine for the unlawful vehicle modification, and you may be issued another ticket which will go on your record.

ECU Tuning - Perform ECU Remapping Yourself.

With the advent of modern technology, even the cars have been made smart and their performance tuning has been made even simpler. Now a days engine tuning can be performed via computers. Car engines can be made more efficient, producing more torque and power and become economical as well as far as fuel consumption is concerned. This all results can be achieved by remapping your car's ECU settings.

Now a question arise what actually is ECU remapping?

Before telling you about it lets talk about some fundamentals. Different car's performance parameters are now judged by sensors embedded at various places in the car. These parameters may include ignition timing, fuel consumption, air flow, throttle position, crank position e.t.c. All these are closely monitored via sensors and their performance reports are send to car's engine management system or electronic control unit (ECU). So ECU basically is a software program which process the signals send by the sensors and helps in better performance of the car in any given condition.

Having said that, the question is automatically replied that why you should have your ECU remapped. Of course for better engine performance. The car manufacturers do not always tailor make their ECU settings at sports performance level. It may sound weird for all car enthusiasts but its a fact. The logic behind it is that why would a granny still able to drive or a mother who drives along with her kids, would require a high performance engine. So they address the concerns of all the end users and make sure that their product is well enough for almost every conditions.

So ECU remapping can be done by just over writing the existing software program of your car and replacing it with a more tuned software, best fitting your conditions. The remapping, until recently was done by removing the existing chip containing the software. It has been made easy after the advent of serial port remapping, and now ECU remapping can be performed by just plugging and overwriting engine map by a better sports performance version in to the serial port.

Tuning ECU is a simple performance upgrading but it may become complicated if you are not aware of your car's specification and would end up in creating a mess if you do not pay consideration to the conditions, the car will have to endure. If you are a newbie and want to perform a rather non professional remapping, I would advise you a simple tool best fit for this purpose. It is known as "Galletto" and use to read your car's ECU tuning file. It's available at more or less $100 from the internet. You need to connect this tool with the obd socket and can be used to diagnose any fault in the car. When the information in the ECU tuning file is retrieved you need to edit and amend it according to your desire using a better tuned software program. But be careful here as the information would be in the form of binary numbers. The software programs which are used to edit these information can be either "race 2000" and "winol". Don't forget to put back tuning file back in to the ECU after you are done.

ECU remapping do have some fuel implications if you are looking for an increase in engines power and torque. However an car can be tuned to an optimum level to save fuel and raise the power and torque as well. The results of the ECU tuning vary according to the engines on which you performed the remapping.

For a turbo charged petrol engine, you can achieve an increase of 20-30% in power and 20-40% in torque. The increase is about 10-15% in power and 15-20% in torque when there is a normally aspirated, non turbo petrol engine. Similarly turbo charged diesel engine ECU tuning may yield a result of 25-50% and 50-75% rise in power and torque respectively. With all these engine upgrading, high power, more torque and better fuel efficiency, why would you not go for DIY ECU remapping?
