New B6 / B7 S4 4.2L Ignition Coils

Is your engine throwing a misfire code? The problem is generally a failing ignition coil. Ignition coils provide spark, which is an essential step of the internal combustion process. If the spark is faint or nonexistent, power will decrease, and your engine will experience misfires. Moreover, as a vital component of your ignition system, coils should be changed every 40,000-60,000 miles. If you're experiencing misfires or ignition-related faults, or if you're due for a new set of coils, choose ECS Tuning Performance Ignition Coils for a durable, long-lasting upgrade that is sure to earn back lost performance.

ECS Performance Ignition Coils are an excellent upgrade for vehicles of all performance levels. These direct plug-and-play coils provide greater spark energy than factory ignition coils, resulting in a stronger, more consistent spark. The attractive red housing with ECS Tuning etched resin complements any engine bay.
