K&N dynamometer testing shows a 4.27 horsepower gain at 7200 RPM. This is well over a 10% power gain for power you can feel. K&N’s air intake design has lower restriction than the factory system. Once installed, you will notice the benefits of a less restrictive system.
The 63-1123 air intake system replaces the stock airbox and intake track with a complete rotomolded intake tube, a powder coated aluminum airbox and an oversized K&N high-flow air filter part number RU-4960XD. The K&N air filter is washable and reusable and provides excellent filtration. It is also pre-oiled and ready for installation.
The powder coated black heat shield assembly helps prevent rust and corrosion and isolates the K&N air filter from the engine compartment. This way the K&N air filter receives a consistent flow of fresh air.
There is also a K&N supplied remote mounted crankcase breather which helps keep the air filter cleaner and helps to dissipate the extra heat and oils which generate from crankcase pressure. Installation can be performed in 90 minutes or less. Take a look at our 63-1123 installation video to see all the steps involved.
A black K&N DryCharger filter wrap part number RX-4990DK, is also included for increased protection and longer service intervals in extreme dust or wet conditions. Jetting modifications will be necessary to obtain maximum performance. The 63-1123 is covered by the K&N Limited Warranty for one year.
