In principle, as long as you buy the correct heat range application for your engine, I think it should make no difference what brand you buy, but I have to admit that I've heard nothing but great things about NGK plugs. The speed shop that installed my crate engine only uses NGK.

Call the NGK tech line tomorrow during business hours. They will use your engine specs to get you the part number for the proper style and heat range. Their techs are VERY good.

I went against everyones opinion on this one. I've had a pinging issue forever. The chevy dealer couldn't fix it and blamed it on the cam & head combo. I switched to a set of 43 heat range plugs and BAM problem fixed! Cost for plugs $15. Being able to slam the accelerator pedal anytime I want with no fear of detonation....priceless.

Have been using NGKs for 6 years. Slightly shorter than the delcos so protect my leads better from my headers!

Is it a high dollar plug? Whats the price of a NGK? iIf it`s more than the correct AC plug then it must be. Also 'Trick plugs' , are just that. a trick plug and nothing more. Too many people on this and other boards believe the more it costs the better it is. Wrong, not necessarily so...
little post scrip here,.. or run on...
how about those multiple tip plugs, how are you going to set them? You cant, Therefore the stock plug recommended by your manufacturer {Vettes, GM} is the best to use. Still on the soapbox, ALWAYS set the plugs at .035. not 040, not 060 nor 080. for PERFORMANCE it`s .035.

I called that tech line for NGK and gave them the specs of my new engine, and they recommended a specific plug for my needs. Oddly, they also suggested .045 gap.

Has anyone shown any ACTUAL proof--dyno testing, et's, etc-- that foreign or speciality plugs are better?
