Review: Great quality, best price - Have used these since I purchased my Focus ST and Ecoboost Mustang. I have ran them since stock and tuned. I change spark plugs every 10 k miles. My Focus is big turbo pushing 25 psi on e30 and does not misfire during wot pulls at all. Mustang is stock turbo e30 and no misfires during pulls as well.
Review: Great Spark Plugs!! - As described. They came with a .038 gapped. Had to adjust a little bit
