i know i have heard lots of peole say that bosch plugs are no good for honda's and they are basically made for domestics. ngk and denso are supposed to be better right? check this out:

bosch platinum vs. denso irridium plugs

bosch does almost as good as denso at 1/4 the cost. the site doesn't say which engine its running for this test but i'll take their word for it since they deal in imports. i was about to waste $60 on denso, now i'll keep my bosch.
