I dont remember which NGK's I got but they were awful. Ed Wright told me NGKs suck for boosted cars. They were causing misfires and some other problems with my car. Ed Wright suggested Autolites. I switched and it solved the problem.

With the proper tuning, you shouldn't have any trouble with the NGK TR6's. I have dyno tested back to back with the iridiums and saw ZERO change. Save your money there.
