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.

Customer Feedback

Did exactly what I expected it to. Bought one for my Avenger a few years ago and loved it. Just recently bought this one for my Ram 1500 and its still just as great.

Only reason I didn't give it 5 stars is because of some confusion experienced with installation instructions. For example, it required the use of an 8mm socket for removing bolts off my airbox mounts (2011 Ram 1500 4.7)instead of specifying 16mm. Other than that, I am pleased with its immediately-noticeable newfound power and the sexy sound it makes during acceleration.

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.
