Subaru STI - Ignition Systems

Fitment Includes: 2004, 2005, 2006, 2007 Subaru STI


Ignition Systems play a giant role in the overall performance of your vehicle whether you be naturally aspirated, or if you have a turbocharged platform like the EJ in your Subaru STI. When you add modifications that add more power and especially more boost, you need to run the right plug heat range and the right plug gap, and certainly enough spark. If your current ignition system cannot keep up with your power levels, you will run into detonation issues, as well as misfires in the upper RPM range. Here, you will find spark plugs of all various heat ranges to suit your fuel and boost levels, as well as coil packs to make sure that you have a smooth powerband throughout the entire RPM range.
