NGK Tr55 or 6s? OK heres why I am in between, and maybe someone can help me decide. I went to the track the other night in my bolt on car and I have lost about 5-6 mph in the traps. I am on original 99 plugs ( 40k miles)....yea time to update that.
So I am still researching what spray kit I want, and will be spraying by October or so. Should I just install the TR6s now? Or should I do the Tr55s until the day I spray?
I was mainly wondering if there would be any negative consequences I should know about if I just do the one swap of NGK tr6s about a month or two before I start spraying.
Who wants to change plugs twice??

I've had tr6s in my car for over two years, and I'm just now getting around to installing my nitrous kit. No problems at all here
I did swap in a fresh set of tr6s a week or so ago though. Haven't had the car on since I've put the new ones in though (missing a drivetrain right now
