Not a bad product. Low end throttle response is more crisp and responsive. Whistling noise at 1500 rpm's is kind of cool, but could be annoying to some.

I have had these before on V8 engines and did not notice much improvement. However on my V6 Tacoma the low end torque is much better and throttle response seems more crisp. It does seem like MPG is a little better as well.
