Thats a good point...I mean they did show you the dyno numbers and supposedly waited equal amounts of time between allowing cooling. Started the runs at the same coolant temp and stuff. Im very skeptical and even if they work like they say they would probably be too hot for my car. Buddy of mine put the new Bosch fusion plugs in his jeep. He has never had a single problem with it and it only has 42K miles on the motor. He put them in and the motor started missing and backfiring, he got a CEL, and a knock sound. He had to go to the store manager to get his money back after showing him what the diff was between the fusions and stock plugs. He ended up putting NGKs in it and it runs like a champ. NGKs are the answer for everyone!
