Re: Ngk TR55 or TR5 (Huttos98Vette)
Just wondering what is the difference between the two and which one should I install ?
the TR5's are gapped to .035 i think, and the TR55's gapped to .050.

The TR-55 is preset at the factory for a gap around .060", which is spec. for the C5 ignition system. Increasing the gap of a TR-5 can be done, put the ground post would not be parallel to the tip. Use the TR-55. :cheers:
