Does anybody have these in their civic?? I heard they are good for tunning the motor to get the most out of it and to make the most use out of high octane fuel. Where would be a good place to get one of these and how much are they in price approx??

 

check out or affiliates RT or KSR or call joe at altec

They are around $150-200 depending on application.

Can kill your gas mileage. Don't know if u care about that but its something to consider.
