What is a spark plug?
Most of you have heard of a spark plug, and for those of you who have, but are not sure what it does, we will explain here. A spark plug is a high voltage bridge for your cars ignition system. The spark plug wires send an electrical current down into the spark plug. The spark travels through the plug, and to the tip. Once it reaches the tip the current sparks once it reaches the gap, and ignites the fuel and air mixture in your combustion chamber. The more efficient and powerful the spark, the more of the fuel and air mixture it ignites. This results in smooth and powerful performance. As the spark plugs age, the power of the spark decreases so you lose performance over time. We recommend to replace your spark plug regularly.

How many spark plugs do I have?
You have one spark plug per cylinder. If your car is a 4 cylinder, then you have 4.

Steps to replace your spark plugs

Before you begin, make sure your engine is cold and that you have the proper tools. You will need a ratchet wrench, 12 inch socket extension, and a spark plug socket for your specific car or truck.
Now that you have the tools, you will need to find your spark plugs. All you need to do is fine your spark plug wires. Follow the wires from your ignition system to your valve cover or spark plug cover. For 4 cylinder or inline engines, you will have all the spark plugs accessible right from the top of the engine. For V6, V8, V10 or V12 engines, you will have half of the spark plugs on one side, and the other half on the other side.
Don't pull your spark plug wires off the spark plugs until you first mark which wire goes to which cylinder. If you don't want to go through this hassle, then you will need to do one at a time. This is because the spark plug wire is designed to spark a certain cylinder. You do not want to ruin the sequence of the wires, it will cause your car to run very lumpy, or not at all. Pull the wire gently, trying to grab it by the rubber boot. Be careful not to pull the wire right out of the boot.
Now that you removed one of the the spark plug wires, get your tools, and remove one of the spark plugs. Be sure your spark plug socket has the rubber or foam insole so it will grab the spark plug once it's loosened. Loosen the spark plug, and pull it out.
At this time, we recommend to examine your old spark plug. The end should be black and sooty, but not too sooty. If it looks like its simply drenched in soot, it means you are running too rich. If your spark plug end is white or has oil on it, this could indicate other engine problems.
All of the spark plugs that we sell come pre-gapped, so you do not need to worry about gapping the spark plugs. They are ready to be installed. For those of you who want to still double check this, please be our guest. For those of you who have a special build, or special needs, you may adjust the spark plug to your specifications. Otherwise, place the new spark plug into the socket, and put it down into the cylinder, gently. Tighten the spark plug by hand until it's snug. You would want to use a torque wrench at this point to ensure proper torque, but usually make it tight without overdoing it. For those of you who don't know your own strength, we highly recommend a torque wrench. Ask in our forum for the specific torque for your application or look in your owners manual.
Put the spark plug wire back on the new spark plug
Repeat the steps for the rest of the cylinders.

Do you sell colder or hotter spark plugs?
We do sell both colder and hotter. Check our catalog above for your specific application. Normally we have the replacement plugs, same as that came from the factory.

Will using aftermarket, high performance products void my warranty? No. Your warranty will not be void by simply using a performance spark plug. The dealership would need to prove that your spark plug is what actually caused any type of problem your car might have.

How long will my iridium spark plugs last?
Our experience has been that iridium spark plugs such as the Denso or NGK will last about 70,000 to 80,000 miles on an engine that has not been modified.

I added nitrous to my car. Can I still use platinum spark plugs?
We do not recommend for you to use platinum spark plugs with nitrous. If you have nitrous, we recommend to use the iridium plugs.
