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 only 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.

 I was skeptical purchasing this product but decided to give it a shot anyway and am glad I did. Received the intake kit for my 2002 Dodge Ram 2500 with a 5.9 diesel motor. Installation was a breeze. It took approximately 35 minutes from start to finish to install. Took the truck for a test drive and noticed an improvement in the acceleration. It has been a few weeks since I installed this product and am now seeing a small increase in fuel mileage. A bit pricey but a great product that I would recommend to others.

 The performance intake kit was very eazy to install on my dodge 3500 12v diesel truck and sounds great with a turbo and more power. Thank you.

 The air filter and housing fit my dodge truck without any problem, the installation took about an hour and have had no problem with anything coming loose or falling off. The K&N air filter lets the engine get as much oxygen as needed without restriction, and I will never have to buy another air filter again,
