What do you guys think about them? Thought it might make a good discussion.

You know me I hate any thing that claims power increase with out Non-Biased dyno results

i did take the time to search around for a few back to back Dyno videos... Some where E3 Related others were fully independent. Horsepower/TQ gains everywhere from 3-15hp/tq in everything from Motrcycles to stock engines to fully build V8s.

What does this do for a Turbo Engine?

Also I have seen similar gains in other vides i found using just other companys premium plugs such as NGK.

Im one for only sticking to plugs recommened by the Owners Manual but Cheap Horsepower is Cheap HP
