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


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.
 
Way to cold... = ?!?!



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
