2008 Chevy Colorado, 3.7L The horsepower gain is awesome, paired with a Jet Stage 1 Performance chip and a Jet Throttle Body Spacer. However, I had to cut the intake tube between the box and the throttle body about 5 inches and had to compensate the angle of the throttle body with a 22 degree elbow from Spectre to make the Volant fit with smooth transitions in the plumbing. I read that others had trouble fitting the box, but I didn't suspect the extremely poor fit of the intake tube. The vent tube to the valve cover was also too short and I had to buy a longer rubber hose for that. Maybe I got the wrong intake tube, I don't know, but it looks and works sweet with the chrome 22 degree transition tube feeding into the throttle body.

Was hesitant at first to spend this much money to replace something that worked fine, but it does make a difference. My mpg has increased by about 2 or so. Very quiet when driving normal. When you need to go and stomp down on the gas, you do get an edgier sound which I like. Would definitely recommend this product.
