Review on AFe Power Silver 46 33009 Throttle by Pedro Curtis

Delivery was quick. Paid a little extra for faster delivery. Ease of installation. The instructions were clear. I also install a K&N cold air intake at the same time. Definitely a performance gain after installing both updates. The problem is that the spacer emits a very annoying howl at low throttle. Almost to the point where the spacer gain isn't worth the noise it makes. The cold air intake and spacer combination increases fuel economy by 2mpg.
