It's just okay
Looks good. Makes engine louder, but sounds good. Possible power increase. Noticed anywhere from .5 mpg to 1 mpg increase not towing. No mileage change towing. Unfortunately the lid doesn't seal to the unit very well. The end doesn't seal to the hole in the fender, there is a wire bundle that prevents it from getting low enough. Nothing keeps it in position like the factory airbox had. It's good, but i expected better for this price and find myself wishing i had opted for the afe instead.
They seem to work. The Volant cold air intake & this seem to have lowered the rpm buy about 200 @ 65 MPH. the hill climb in cruse is really noticeable, a whole lot smoother, again not as abrupt down shift. I chose the spacer because of the air intake. The install is straight forward. Auto Anything has the best deal & is a fast shipper. I hope the info. is a help in your decision.
