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. They've been tested on vehicles from stock power to over 1,000whp, delivering improved drivability and power across the board.
Get 10% more power output than OEM. The increased output means a smoother idle and power delivery throughout the powerband. A stronger spark prevents spark blowout and allows high - boost applications to keep a larger plug gap. It'll enhance any vehicle's drivability!
The plug - n - play fitment is perfect for any EJ20/EJ25 turbo application listed. It can also be used for USDM EJ20 black coil applications by swapping coil boots and adjusting dwell settings.
No tuning is required for most listed applications at any power level. You can simply install them and go. However, professional tuners can get better timing control at higher power levels, releasing more horsepower.
We offer an 18 - month replacement warranty for failed ignition coils with a valid receipt.
Package includes (4) Street Series EJ20/EJ25 Ignition Coils, a Product Info Card, and OTL Decals. There's also an optional Harness Repair Kit with (2) white and (2) black replacement harness connectors to ensure proper ignition system operation.
Direct fit applications include Baja 2.5L Turbo 2004 - 2006, Forester XT 2004 - 2013, Impreza WRX 2004 - 2014, Impreza STI 2004 - 2018, Legacy GT 2005 - 2014, Outback 2.5L Turbo 2005 - 2009, and Saab 9 - 2x Aero 2006. Tuning is required for Impreza WRX 2002 - 2003 black coils.
Using the OTL Street Series Ignition Coils is easy. First, make sure your vehicle is turned off and cool. Check if your vehicle is one of the direct - fit applications. If it's an Impreza WRX 2002 - 2003 with black coils, you'll need to do some tuning. For other listed applications, you can install the coils without tuning.
If you're using it for USDM EJ20 black coil applications, swap the coil boots and set the correct dwell settings. The coils are plug - n - play, so just connect them properly. If any of your harness connectors have broken tabs, use the optional Harness Repair Kit to replace them.
As for maintenance, keep an eye on your vehicle's performance. If you notice any issues like rough idling or loss of power, check the coils. Make sure to keep your purchase receipt as the coils come with an 18 - month replacement warranty in case they fail.
