"I have to say that this product is really awesome, it sounds great and best of all it gives my trucks engine a new line on life. The engine to run's better throughout the gears and runs smoother at idle. Off the line it seems to be quicker, and have i mentioned the way it sounds!!! Also i have noticed about 1 to 1.5 mpg more, so that has helped a little with these crazy gas prices." —George V from Chicago, IL bought a K&N 77 Series Metal Intake Kit for a 2003 Cadillac Escalade.
