http://cgi.ebay.com/ebaymotors/aw-cg...632949&r=0&t=0 What do you guys think. Not bad considering it will give you about 20 HP. You think this is BS? I dont have money for that right now but seems interesting how you can get 20HP with just plugs.

Why am I surprised, you can get 60HP with Type R decals too.

 

I've heard of these. They were in the october 2001 Muscle Mustangs & Fast Fords magazine, page 159. They do say they gave an extra 19 peak horsepower, and up to 30 extra in some parts of the powerband. Note that these were on a supercharged engine. Most of the power came from being able to up the boost to 12 psi. The stock plugs would misfire at 9 psi, so I don't know how much you can expect from a stock engine?

 

Thanks for pointing that out. I mean it seemed like total BS that he got 19HP from that engine. Thanks for the reply man.
