Spark Plug Choices

wow, i feel dumb. That is the tool i was talking about to check the gap, i didn't realize that it opened the gap also.

thank you for all your help. i was kind of
to even ask these questions. I believe the TR55 comes pre gaped @ .045. I've gaped them to .050, but I've also had the same results, just dropping them in out of the box.
Like i said, the "G-Power" (TR5GP) is supposed to be a high-er performing TR5.[/QUOTE]
at O'reillys the difference is less 1.99-2.59 so for .60c more I'd get the platinum and double the life of the plugs that is if the tr55 is a copper plug - I'm pretty lazy so why replace plugs often and in 4th gens its NO fun at all!
