The K&N 57-1511-2 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram pickups models. K&N 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 57-1511-2 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 air intake system accommodates the factory crank case vent hose, EVAP assembly and A/C line. The oversized 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 the existing factory mounting points and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

  Great product, paired this system with a flowmaster cat back exhaust system and gave my 2001 Dodge Ram 1500 a new lease on life at 135,000 miles. I can hear the engine breath, wow. Thanks from me and the truck.

  Took a bit to install. But after I drove around, I could tell the difference. Really good product.

  Having already experienced K&N air filters on all my past motorcycles(mx/supermoto) I knew that I couldn't go wrong with an intake system for my old truck. Purchasing this 57-series intake for my 98 ram 360v8/5.9l made a nice clean power gain along with feeling much more responsive in acceleration compared to the old factory box...I'm satisfied with this product and feel that it was another good purchase for the price. Thanks K&N

  I added this beautiful part to my '99 Ram 2500 5.9L V8 in one afternoon. Along with my neighbor coming by and talking to me for a bit, I spent all of an hour and 20 minutes installing. Although the destructions that come with it aren't very descriptive, I was able to install with ease. I have to say, hearing the engine come to life after putting this air filter on is an experience all in itself. Just starting the truck I could tell an immediate difference in the sound and performance of the engine. It seemed to breath easier, and it roared to life just as Wolverine did after he got his claws. Getting on the road and giving it some gas was just simply amazing. It snarled down the road with this mean, aggressive sound that only K&N matched with Flowmaster can provide, and it was just simply amazing. It put this grin on my face that I couldn't put away even if I tried. I haven't had a chance to see the MPG difference yet, since I just put it on, but the horsepower gain is blatently obvious just when you start the truck. I read up on other reviews on the OEM filter replacement that they saw a difference in MPG after the computer reset to the new air/fuel ratio. So I'll take that into account since this is a whole new system rather than replacing the air filter alone. Anyways, if this review doesn't help you decide whether or not to buy this product, then good luck to you. I personally went to Advance Auto Parts to purchase mine. Bought it on Saturday. It was waiting in the store for me Sunday morning at 8 then I put it on after church and went for a test drive. If you can spare the pocket change, suck it up and buy it. I promise you will NOT be disappointed!

  I added this to my truck in one morning. I found it very easy to install. All the things I needed were there. I would order again.
