One Step Colder plugs are recommended for cars with heavy modifications. These Iridium Spark Plugs will get your Turbo Subaru running smoother and free up some power through increased efficiency and increased heat resistance.

If you’re making over 300WHP we recommend running these spark plugs over the OEM range plugs.
