Product Reviews      Review part 33-2201

 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.

 Got my KN Filter in April. I drive a 2005 Hyundia was getting 28 mpg. After the filter was installed, which was easy, I am now getting over 31 mpg
