Subaru Black and White Coil Pack Replacement Plugs
STOP USING ZIP TIES!
What It Does: The coil pack plug attaches to, you guessed it, the coil pack. This gives a signal which triggers your spark plug to fire.
Cars It Works On: All EJ turbo and EZ 6cyl Subaru models from 2002-2010 including Impreza WRX, Impreza STi, Forester XT, Tribeca, and Legacy. Also great for EJ20G to modern coil pack conversions.
How to Know if you Have an Issue: Some misfires are easier to diagnose than others. First step, check your connectors. With a simple visual inspection it would be easy to spot a cracked, broken, or disintegrating coil pack plug that could be the issue and should be replaced.
Note: White coil pack plugs (cylinders 1 and 2) are located in the front of your Subaru and Black coil pack plugs (cylinder 3 and 4) are located in the back of your Subaru.
