TR55 spark plugs in 402 Will running TR55 spark plugs in a 11.5 compression ls2 402 hurt anything? I installed them by mistake and I don't want to change plugs again if I don't have to. I normally run TR6's but I picked up the wrong ones.

with higher compression people usually go alittle colder on the plugs but if your tune is very close i don't see any reason it would actually hurt unless it is detonating some. better safe than sorry though.

Infact, if you're not getting any detonation I would leave them in there, because with the hotter plug you could get more power, going to cold and you will lose some. I had TR6's before, but I felt that TR55's would befine, and they were. So, if its working, don't fix it =D
