A quality ignition system is vital in any turbocharged vehicle, especially in the EJ platform of the Subaru WRX and STI. If you add more upgrades that increase the power and boost, you are surpassing the limits of the factory spark plugs in terms of gap and heat range. If you have a weak ignition system or the wrong plug, then you will experience misfires or detonation issues which can lead to premature engine wear. Additionally, the coil packs are a big part of the equation for those of you who are making substantial amounts of power that need a stronger spark output. We carry a massive selection of spark plugs in a variety of heat ranges for the right boost and power application, and we carry a great selection of coil packs for those of you that need the supported spark output. All of which are required for a smooth delivery and power band, especially in a tuned EJ.
