The K&N 77-1570KS is a cold-air intake kit for the 2.4L Tigershark four-cylinder in the Jeep Cherokee KL. It replaces the factory airbox and plastic intake tube with a mandrel-bent aluminum tube, and an oversized oiled cotton conical filter sits behind a heat shield to pull cooler air from the engine bay. The manufacturer says the kit is engineered to increase horsepower and torque, and the silver powder-coated tube is easier to keep clean than raw plastic.
Compared with stock, the larger tube and filter aim to give the engine a wider, less restricted air path. The filter is washable and reusable, so you avoid replacement filter costs over time. The manufacturer rates the filter for cleaning about every 100,000 miles under normal highway driving. For Cherokee owners searching for a 2.4L intake that needs no tune, a reusable aluminum kit like this one is a practical upgrade over a basic drop-in filter.
The manufacturer lists this kit for the 2.4L L4 Jeep Cherokee from 2014 through 2018. The product title references 2014-2015, so confirm your VIN and engine code against the manufacturer's fitment guide before ordering.
Yes. Per the manufacturer, the conical filter mounts behind a heat shield where the stock airbox was, and the kit replaces the factory air filter and intake tube.
The manufacturer states the filter needs cleaning about every 100,000 miles under normal highway driving. Harsher dusty conditions will call for more frequent service.
The manufacturer states that a typical installation takes 60 minutes or less using simple hand tools, and the kit uses bolt-on hardware with no additional under-hood modifications. Reconnect the inlet air temperature sensor and the crankcase vent hose to the tube's built-in fittings, and make sure the heat shield and filter sit correctly behind the shield before tightening clamps. Check all clamps and hose connections after installation for air leaks.
