When I saw the ad for these plugs I got curious so started doing some searches for info. But I will first say they are 24 dollars a peice. That is just crazy!!!!!!!!!! For that price they better drive the car for me. Second I found a forum where a guy with a corvette got the company to send him a set to run on a Dyno. The company claims somewhere like a 10% gain in MPG and HP he said he got no gain HP at all compared to his original plugs and a .3% gain in MPG which he said could have been related to his driving style while the plugs were in. Now this is one guy and one car but no plug is worth 24 dollars. The savings in MPG would have to be greater to be able to recover the cost of the plugs. They only last for about 50,000 miles.
