What kind of spark plugs are most of you centri guys running and how is the drive ability with them? Going to be around 10-12lbs of boost in an MMR 900 block. Thanks in advance.

NGK TR6's. Driveability is almost stock like.

+1 on the TR6's @ .028-.030"

NGK BR7EF's.. I had issues with the TR6's.. BR7's are awesome

^^ My tuner took my TR6's out and replaced them with BR7EF's and I havnt had a prob yet.

If you can't run a TR6, then somethings wrong. A BR7EF is slightly cooler than a TR6, but a TR6 is plenty cool enough for more any Modular boosted setup.

I've used TR6s for a while now with no issues.

Let me clarify something wasn't wrong.. It stumbled a lower rpm like some people who run them have.. Driveablitly was much better with the 7's..

Well ill put it thise way the tr6's in my car were bad....not in causing problems but i guess some of the plugs were messed up. And I think my tuner just happened to have the others around the shop and he used them to fix my problem of the car having a bad miss down low and stumbling. I had 0 issues with the Tr6's. Thats just not what i have in my car right now

so for 20+psi of boost which one's are better, the TR6's or the BR7EF's?

BR7EF's.. With that much boost..

My TR6's are still in @ 24psi....
