Replace OEM part numbers 22433AA541, 22433AA480, 22433AA540, 22433AA640, 22433AA602 with our OTL Street Series Ignition Coils. These coils are designed for the Subaru EJ20/EJ25 turbo platform. We've tested them on vehicles from stock power to over 1,000whp, and the results are amazing! They offer 10% more power output than OEM, delivering smoother idle and power across the band. A stronger spark prevents blowout and suits high - boost setups. It's a plug - n - play fit for most EJ20/EJ25 turbo applications, no tuning needed for most models. You can just drop them in and go. We offer an 18 - month replacement warranty with a valid receipt. The package includes 4 Street Series EJ20/EJ25 Ignition Coils, a product info card, and OTL decals. There's also an optional harness repair kit to ensure proper ignition system operation. Fits many Subaru models like Baja 2.5L Turbo (2004 - 2006), Forester XT (2004 - 2013), etc. Tuning is required for Impreza WRX 2002 - 2003 black coils.
Using these OTL Street Series Ignition Coils is easy. First, make sure your vehicle is one of the direct - fit applications. For most EJ20/EJ25 turbo models, it's a plug - n - play installation. Just remove the old coils and put these new ones in their place. If you have a USDM EJ20 black coil application, you'll need to swap the coil boots and adjust the dwell settings. You don't need to tune your vehicle for most models at any power level, but it can give pro - tuners better control for more horsepower. Remember, if you have an Impreza WRX 2002 - 2003 with black coils, you will need to do a tune. When it comes to maintenance, keep an eye on the ignition system. If you notice any broken tabs on the connectors, use the optional harness repair kit to replace them. And don't forget, if your ignition coils fail within 18 months of purchase, just show your valid receipt and we'll replace them.
