    Ignition Systems

    If you have big air and tons of fuel getting shoved into your intake, you better have the ignition system to light it all off or you are going to get a whole lot of nothing. Yes, you can actually blow out the spark if you don't have the right parts in place. Don't be that guy who sputters at the top end and watch that other guy drive out of your life. Get a solid performance ignition system for that high power Subaru WRX/STI, with upgraded coil packs, spark plug boots and spark plug sets. Air, Fuel, Spark. You must have it all!
