Nice set up but the filter that came with it was a K&N filter and doesnt look like the filter in the picture. If i wanted a K&N i wouldve gotten it. Filter was hard to put on kept slipping off when i tightened it. Cant really say about mpg and horsepower due to flowmasters installed but the sound makes the truck sounds mean when you hit the gas hard. There is a slight whistle sound. Other than that sounds and looks good.
aFe Magnum Force Cold Air Intake System
Have had my aFe Cold Air Intake installed on my truck for about a week, and I think it is a great addition to the engine. I notice that the truck has a better starting response as well as a much better accelerating response when at cruising speed. It has not set off the check engine light as I heard that the K&N does with these trucks, and very glad I did. I am very pleased with my choice of this brand and model. Installation instructions were not for my model, so it took much longer to do.
