OTL Performance Coil Pack Set 2015-2023 Subaru WRX / 2017-2021 BRZ

These are the Off The Line Performance Street Series Ignition Coils. Once you start making more boost and more horsepower, you will have to upgrade your ignition system as a proper spark output is a key attribute when maintaining a smooth power band throughout the RPM range while making big power numbers. 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.

• On the FA20 platform it has come to the attention of OTL that the rubber gasket / seal in the chassis side of the coil pack connector can be dislodged upon removal of the factory coil pack. As a result when you reinsert the connector into the new OTL pack the gasket can become pinched or cut causing an improper connection. It is imperative that the seal be inspect prior to installation of the new coil packs and that when you are installing the new packs care is taken not to pinch or cut the seal.
