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.
