The K&N 57-1537 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram 1500 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-1537 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory air temperature sensor and a replacement silicone crank case vent hose. The oversized oval cone-shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, a ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

 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.
