The K&N AirCharger 63-1537 air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram 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 63-1537 air intake comes with a chrome topped K&N high-flow oval air filter and a heat shield that installs into the previous air box space. The placement allows air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized 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 requiring only a screwdriver, socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

2015 Ram 1500 5.7L Easy to install, performs incredible. I have a custom exhaust and after I installed the K&N, it gave it that rumble tone I was looking for. Really feel it kick in at 4500rpm.

2014 Ram 1500 5.7 Hemi. I installed this in a little under an hour at night. The instructions could have been better detailed, but once completed, I found my truck to be 10 times more impressive. If you have a hemi, you have to have this intake. It is a night and day difference. Thank you K&N, Now time for a good exhaust system.

Excellent product. I received my new air filter very quickly and in perfect condition. I coupled this K&N air filter with a cold air intake on my 2006 Dodge Ram 1500 4.7L. The throttle response is a big improvement and the overall horsepower seems to have improved. Great job K&N on another great product.
