Review part 57-1537
LOVE IT! Installed it on my 2004 Dodge Ram 1500 3.7L. Quick and easy install, everything fit perfectly and I got a noticeable difference in my mid range power and my fuel mileage increased 2.5-3 MPG, not to mention it really enhances the sound of my Flowmaster muffler too! I highly recommend any K&N intake to anyone, it's definitely worth the money!

After installing this air system (57-1537) on my 2007 Ram 1500 with a 3.7L engine I was VERY upset@! Up set that this is not standard on the vehicle from the manufacturer!!! What a performance difference, should be shipped from the factory with this product. Better performance and better gas milage, about 4mpg!
For me this was a two step process. I was not sure about how this would work, so I first simply bought the air filter replacement element and installed in the factory air cleaner. Right away I noticed a difference. So much so that I bought another one for my wife's car (2002 Hyundai). After running with the air filters for a while, I decided to look into the air-system replacement. It took a few months for me to actually buy the system because I guess my truck in not a true 2007 but a 2007-1/2 or 2007-3/4. The actual engine configuration is that of a 2008. So when I down loaded the install manual from K & N's web site the crank case breather did not look like the 2007 described. Once I determined that my engine confirguration looked more like a 2008 I was home free. I bought the unit and just love the performance!! With the price of gas as it is I love the extra 4 mpg as well.
