The Dyno results are claims made by the manufacturer. The only way to get an accurate HP dyno result you would have to replace new for new. Most of the Dyno results are from cars with 100,000 miles. Of course you will see gains in HP when you replace a old tired plug with a new precious metal plug.
The big question is wattage. What wattage are they producing and how are they producing this without a Flux Capacitor or the help of David Copperfield?
im going s/c and these just came available at my part time job at Autozone, i can pick these up for $80 (all 4) so the price is decent, but i can't find any info on the heat range for my setup or if this doesnt apply to this brand, no clue....anyone?
Pure snake oil! if you want to waste your money go ahead in one of the tests i saw the difference was like 1.26 horsepower and that was on a 300 hp vehicle. Thats not enough that could be dyno error. I had a chance to buy them for 15 shipped on the mazda 3 forum and didnt. over 50 people did however and nobody posted again on the website about how "good" they were. In fact the only post was somebody that received one that didnt work.
i bought a set of these. from what i've seen on tv and magazines, they are supposed to add hp and increase fuel ecomomy. i haven't experienced either of these. according to my gas mileage meter, i'm still averaging 29.5mpg ranging from stop and go traffic to 20 miles at 62mph for my 50 mile one way drive to work. they're also only good for around 50,000mi. did i get ripped off... sure did. but, if it would have worked, it would have been worth the money. its all about trial and error. if it costs a few bucks, well, it costs a few bucks.
