I am thinking about switching to a set of Denso plugs and removing my TR6's. My question is which ones should I get, I have seen 20's and 24's. My mods are listed below. I am going to stay with the 4lb pulley for now and in the near future I am going for a set of LT and a cat back system. Later on I am thinking about a Cobra R pump, electric fan, and a TB, but that is at least a year away. Just would like some opinions on which ones I should use. If I do go to a 6 lb pulley will the plugs for the 4lb pulley still be correct?

 

I don't know the answer but, why are you wanting to switch?

 

Have been running the BR7EF NGKs and they work well. I had some misfiring at idle and am sure at WOT. I also seen this with the TR6 NGKs. My new motor is going together with the IT22s. They are the ones that I would suggest.

 

I have heard good things about the denso's and eventhough the NGK are better than stock there is still a miss that I want to get rid of.

 

Sal(PSP) recommends IT24s for 5+ extra lbs of boost--gap them at .038".

Right now after reading alot of post I am leaning towards IT22s or the IT24s. Since I am running a 4lb pulley I believe the 22's would be better or should I bite the bullet and get the 24's incase I ****ch to a 6lb pulley.

I will be moving down to Milledgeville begining next month and would like to meet up with you at the track once I get settled in.

 

I am running 6+ more pounds of boost and will be using the IT22s.

 

IT22's here too as per JL
