I will be totally honest, since the purchase of this K&N Intake my horsepower has gained drastically. I have spent more fuel, but ONLY due to the fact that I have not been able to get my foot off the accelerator with increase of horsepower. I felt it immediately as soon as I got on the road. Very satisfied customer, despite all the opposing criticism that nearly convinced me to not place this purchase.
