Thread: NGK TR on stock GTP

Im changing my plugs this weekend. I was told to pickup NGK TR6 plugs. They will work ok correct?

The reason I ask is because I know they run a degree cooler than stock. Just wanted to make sure I would be ok

youll be fine, but with a stock pulley you really dont need them. you should be running as hot of a plug as you can.

Cool thanks Bio

TR6's are way to cold, buy TR55 plugs.

I ran TR6's with my setup and they were to cold, I switched to TR55-IX iridium plugs and they are great.

Way to cold... = ?!?!

i still dont get why people just dont run copper plugs. they are cheap as crap and do the best with knock reduction.

well what copper kind would u recommend?

autolites.

i run 104s because im not running that much boost, but when i start getting into what i will be come summertime i will run 103s.

do they need to be gapped or are they good to go ?

Plugs will get fouled quicker as well as crappy mpg.


I ran them with my exact setup which warrants a cooler plug that your setup and I'm speaking from first hand experience. TR55's are already colder than stock plugs by .5

i still gap my autolites after i buy them.
