Anybody use these or know if they are better for our bif turbo motors? I read a big thread about how they improved torque and idle, but none of them was a turbo car. Let me know. Thinking of buying a used set.
Thanks

my tuner told me it's a junk that waste of money...

 

Anybody else? Tuners??

 

Just use the coprrect spark plug and gap and you will not need them.

Some people swear by them others don't think they do much. If I were going to the dyno on my low milage SC car I would think I would buy a set and see for myself, and if they did nothing just sell them used.

Do they do anything? I can't say for sure unless I try them. For some they are really expensive and don't warrant the cost. I might try them some day for giggles, but don't have any reason to go to the dyno so buying them is not in the plan.

Hell, I paid $600 for a Mugen header used and can't tell if it did a darn thing for me. I don't care, its just a hobby.
