Review on Boost Performance with Airaid 300-637 PowerAid Throttle Body Spacer by Eric Wohlman

Revainrating 5 out of 5

Easy installation. Longer mileage

Easy to install. Best run. Quiet sound. I've had these in the last 4 cars I've owned and I really like them. Some whistled a bit but nothing that some people complain about. It's barely audible at cruising speed and is really the only time I've been able to hear it. There is no "cool turbo" or "belt squeak". I also have a K&N Performance air intake kit which also helps with mileage.

Pros
  • Comfortable to use
Cons
  • Unfashionable
