The part is apparently good quality. It was a simple installation, but the directions on how to mount the bracket were fairly unclear. However the part works well and creates good torque in the upper half of engine revs where the stock intake was lacking. It also creates a better deeper sound in those rev ranges as well. Overall I am impressed and satisfied.

It performed alright. It gave me an extra mile out of each gallon. A slight increase in throttle response. Horsepower gains were unnoticeable (if there were any). The sound improvement was the most impressive feature. A little too expensive for what you can get out of it. Would rate higher if price was lower. Would rate lower if sound was not improved.
