So I have read my eyes dry on this issue and still have not come to a conclusion. All of the threads are over 3 years old and there is no solid information. What spark plug is a good alternative to the stock EVO 8 plugs. I was leaning to the BPR7EIX I think... What does everyone else say? I have a tune, TBE, Intake and that is it for now, boost peaks around 22PSI. Thanks

 

You setup sounds almost identical to mine. My tuner, Tamer (4wstuning), will suggest NGK BPR8ES gapped @ 0.026. I've used Iridium plugs before, and I can't justify the extra cost.

 

Ok cool, now how often do you change them?

 

i use the same plugs as "bigben" does,i have mine gapped a little closer then that but i change mine every couple of months...there cheap so why not...

 

OK so everyone stepped to a colder plug? Are there any advantages to this, and what about the gap? I have seen everything from .030-.023, is it really that big of a deal? Thanks
