Re: WTB - Plenum insulator plates
Not to Hijack a thread but what is the advantage or disadvantage to these spacers. I've never really got a straight answer from anyone. I have a set on my car that a previous owner had put on and I thought about removing them when I do my first plenum pull if they are not helping the performance of the car.
Steve,
