My FPR and damper are black, which I think is oem. So I'll order replacements. Who makes the best ones? Also, my cars exhaust has faint little "putts" every so often. I don't think it's a true misfire because when I pull a coil the engine runs worse and rpms drop. I was assuming it's becuase the EPROMS tend to run super rich, but I'm not positive. Was going to swap my JWT for a specialty Z chip in hopes of solving the issue.
