what are good spark plugs to eplace the stock one's... i read here somewhere that the plugs go bad quickly... no idea why... are denso radium's good.?

 

you cant be serious about this question. iam noone to call some one new yo. but seriously. theres millions of this same question all over.

But here it is from me on my personal set up. Iam running 21lbs of boost and run the BP8's gapped at 23

youll have to figure out what your willing to do. I gap shorter and change plugs more often, about ever other oil change. Go with some BP7-8's youll be good.

The question you then have to look for is what your going to gap them at.

Good luck man. and welcome

 

Do you have an VIII or a IX? It makes a difference.

I haven't replaced mine yet, but from what I gather, on a stock IX, you should use NGK ILFR7H Spark Plugs (0.28 Gap). After you mod (TBE, MBC, Tune) you can use NGK R7437-8 Spark Plugs (0.26 Gap).

At least that's what my research has shown... sound right guys?

 

thanks shamlesscookie... and yea it is a stock IX MR...
