The Off The Line Performance Ignition Coils have been tested on vehicles ranging from stock power levels to vehicles making over 1000 horsepower. These are direct replacements for your factory ignition coils for a plug-and-play installation.

Important Notes: 

• Coil packs are a common fail point on many Subaru models as the car ages. Although they do not resolve all issues, proper diagnosis is required to ensure that the coil packs are causing the fault you are experiencing. Things like the spark plugs, piston rings, cylinder walls should be properly  inspected to ensure that the solutions you are attempting to deploy resolve the issue and don't add another dynamic to the problem.

Tune Required:

• Impreza WRX 2002-2003 black coils
