Review: Make sure you gap them! - Decent plugs for the price, but make sure you gap them! Gas milage seems good. They don't come pre-gapped. I Assumed they did and threw them in the Audi A4 as i couldn't find my gap tool. The car started, idled and drove fine but stuttered badly when hard accelerating. I pulled the plugs, checked the pre-set gap and they were well over spec. Decreased the gap and now drives perfect. I'm used to the pre-gapped auto parts store plugs out the box, my bad. Overall good plugs as long as you keep that in mind. Too early to tell how long/how well they'll perform.
Review: Quality Part. - Exact fit, works great.
