Spark Plugs

Spark plugs are an imperative maintenance and performance component for a properly running vehicle. If you have a misfire or hiccup in your vehicle, then don't waste time trying to diagnose all of the major scenarios while overlooking a simple factor. People often forget that spark plugs should be re-gapped or ran a step colder when turning up the boost, or performing moderate bolt-ons such as a larger turbocharger, upgrading the exhaust system, or running a custom tune. Spark plugs should also be changed after a certain amount of mileage, or if you have been running race fuel for a while because race fuel can foul the plugs out.

RallySport Direct carries a wide variety of spark plugs for many turbocharged and normally aspirated applications.  You can choose from one step colder, iridium plugs, or stock like replacements. Spark plugs will come pre-gapped for some applications and depending on your tune, your build, or even your gas type or where you live because of elevation changes, there is a right spark plug for your car.

Choose from brands such as NGK, Bosch, Denso, as well as HKS. Make sure when shopping for spark plugs, that the rest of your ignition system is up to par. RallySport Direct also carries a good selection of coil packs, grounding kits, as well as spark plug boots.
