Jeep Spark Plugs

The main function of spark plugs in the internal combustion engine is well-known: everybody can tell that they provide a spark to ignite fuel in the cylinders. However, not all drivers are aware that these parts play a further role in transferring part of heat produced during combustion, helping to keep engine temperature at the optimal level. Today, there is a wide array of different spark plugs, with many combinations of materials, geometry, and design to meet various requirements. Whether your Jeep is a rugged off-roader or a refined SUV, you can find a perfect set of plugs to restore or boost its performance.

The material constituting the central electrode and the ceramic insulator's shape define the type of the plugs. The electrode can be made of copper, nickel, iridium, or platinum, while the insulator influences the amount of heat transferred from the combustion chambers. More effective heat transfer is mainly needed at high revs; this feature is peculiar to so-called cold plugs whose own temperature remains not too high. Hot plugs reach higher temps; they are good for average driving and short trips, as a higher temperature of the plug's tip contributes to its self-cleaning. Whatever your driving goals and engine model, we have a large selection of premium quality Jeep spark plugs built by renowned companies and offered at affordable prices.
