Why would iridium be recommended for supercharged applications then? Or are you just talking about platinum? Platinum for sure is very bad to run with boost. I know because I melted some ruining my engine on another car.Platinum plugs (and Iridiums) were introduced to provide longevity (60k-100k+) to vehicles compared to copper plugs which foul after 15k-30k miles, but they do NOT dissapate heat fast enough (which leads to pre-ignition/detonation) and do NOT provide a "better spark" like they have claimed...with their "fine-wire electrode" (which only causes problems).
No you have to take the fuel rail off but its not the bad, only a couple of nuts. Just get a plug that is a step colder from stock to prevent detonation.Yeah i wasnt trying to get any platinum or anything like that. I had heard that about them (predetnation). Im probably gonna go with NGK. Dont suppose anyone has figured out a way to take out the plugs with out removing the fuel rail? hahaha. This is gonna be fun. Nice ride you got there Matt. I love that color combo (forrest green with gunmetal/dark rims) Thats actually kind of what I was looking for but I couldnt pass up on my stang haha. That **** is sharp though.
They're recommended right here:Ive never heard of iridium being recomended for boost and you actually dont have to take the fuel rail off. You just remove the coil hold down bolt, and you can slide the coil out from under the rail. Then just use a socket with an extension and a swivel to get the plug out. Trust me Ive done it plenty of times. And thanks for the comments echo!
