I run the B8EFS plugs in my car, but I have the gap at .025. No negative effects running these plugs on the street. My car didn't like .032-.035 when the nitrous would hit it wasn't happy, acted like it was blowing the spark out. I have much better results with .022-.025.

good reinforcement on what everybody said, I was afraid originally the 8's would be hard to idle but never been an issue. And no more burning up ground straps lol. good luck, I gap mine at 28
