turbobluestreak Posted August 1, 2003 Share Posted August 1, 2003 well I've had good luck witht a set of v power plugs. NGK# BPR6EY-11 thats the same heat range as the stock NGK plug # BPR6ES. It's up to you you also could go with a 7 heat range but I would be worried about detonating with that much boost. tbs Quote Link to comment Share on other sites More sharing options...
