The K&N 57-1525 Air Intake fits some Dodge Ram 2500 Pickup, and Dodge Ram 3500 Pickup models. See vehicle applications link for details.
The K&N 57-1525 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram trucks. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Ram’s 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 57-1525 air intake comes with a 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 filter restriction gauge. The oversized conical 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 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.

Very happy with this product. Have ran K&N products for sixteen years, always great quality of product.

It was easy to install. Do not notice much difference from this and stock. I will have to mention that I had a K&N filter in my stock breather and I haven't put that many miles on it. So maybe that's it. I think the unit is a little over priced as well. But then again it is a lifetime filter.

Just installed this on my 2008 Ram 3500, wasn't too hard to install but schematic picture of the hardware could be a little more crisp to show part locations a little better. Really open up the air intake. You can feel the throttle response is snappy and the turbo makes a great whistle. Overall great product for the money; we will see how it lasts long - term as I have a cross country trip coming up.

Haven't had my K&N filter installed long but I immediately noticed an improvement in takeoff performance. Too soon to know yet about any fuel mileage increase. So far I am very pleased with the intake and filter. Easy installation. Fast shipping.

Great product kind of spendy though. But it's worth it in the long run.
