As much as I like and appreciate our friends over at aFe, I have no idea where they got those numbers. In our testing we found that alone, the intake won't get you all that much. You'll see a slight gain in power, throttle response, and fuel economy. With tuning (especially custom tuning), you'll see much better gains that are on par or exceed aFe's numbers.
We'll take back the intake if there's a fitment or workmanship issue under warranty with aFe. All other returns will fall under our Return Policy.
The cover is available here.
