Ok, I have a DP and exhaust on my car.

When I rev the car, sometimes it will back fire. Also, when no boost is built up and I am driving around it backfires. Any ideas as to why this is happening? Its very annoying, please any info would be great.

I am running these right now: NGK (BKR7E11) Spark Plugs

Should I upgrade to 3330's? Also what gapping would be good?

i run 3330's in my car and it runs really rich, and i have no backfiring so i would try throwing a set of those in and see if it help. the come pregapped at .032 so you should be good with that. if you have an advanced autoparts in your area go there and get a set, you might have to order them but it will be next day delievery and they are only like a buck or so each from there.

My car also kinda backfires after installing my DP, and BCC. I just thought that the problem was that I didn't tighten the srews of the DP tight enough (not using a torque wrench and all). I guess I can go with NGK's 6097's this weekend to solve it.
