K&N 33-2188 Air Filter Product Reviews

I have used the more performance oriented cone style filters, as well as the full on/complete FIPK's on performance vehicles, but this purchase was just a stock panel replacement. Despite the car's age and mileage (154K), the engine runs glass smooth, quiet, and like brand new. Especially with a recent replacement of the spark plugs, wires, timing belt, and synthetic oil change. No possible way to run any better, right? WRONG! I had been considering aftermarket free-flow intakes, as K&N doesn't produce a FIPK for this model, but they were just cone filters installed at the throttle body and thereby sucking in hot engine bay air, as opposed to the factory box that does pull cooler air from inside the fender - SOOO a stock K&N filter was finally installed and I am AMAZED at the increased 'tip-in'/throttle response and ADDED smoothness It runs and feels like a V12. Doesn't matter WHAT you drive or HOW you drive. There IS a difference between stock paper replacements and the K&N filter on ANYTHING. And you don't necessarily have to get a FIPK...you WILL feel a difference with a 'simple' stock replacement

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.
