Very Pleased Jul 15, 2007 I installed the K&N77 in a 2005 GMC Serria and I noticed an instant increase in horsepower. Acceleration is better and I have noticed that towing is better. Engine noise is louder when accelerating but it just sounds more powerful and goes away as soon as you stop accelerating. Installation was easy.
Excellent!! Jan 04, 2007 This filter provided the very noticeable horsepower increase. Highly recommended it, much better MPG.
