To add performance K&N replaces the Wrangler's original air box, air filter and intake tube with an all new air intake system. The aerodynamically engineered non-metallic rotationally molded tube is designed to provide lower air temperature and reduced intake sound than metal tube intakes.

The K&N Lifetime Replacement Air Filter (RF-1048) is protected by a powder coated steel heat shield. The heat shield isolates the chrome top K&N Air Filter from the engine compartment and allows the K&N Air Filter to receive a consistent flow of fresh cool air.

The heat shield assembly is installed into the engine compartment and a bracket supports the tube which is mounted to the engine. Simply remove the factory air temperature sensor from the stock intake track to install the new K&N Air Intake System.

The 57-1553 can easily be installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty.
