The K&N 70-1572 NextGen Aluminum Cold Air Intake is a complete replacement for the factory intake on the Jeep Grand Cherokee WK2 with the 3.6L V6. The manufacturer's NextGen aluminum tier pairs a custom powder-coated aluminum intake tube and a NextGen hybrid air box with an enlarged factory inlet, along with a high-flow oiled cotton filter. Together these replace the restrictive stock airbox and tube with a larger, straighter air path, and the rigid aluminum tube gives a sharper engine note than a stock plastic intake.
Set realistic expectations before buying. The manufacturer's dyno-backed marketing centers on power and airflow, but the specific gain figures for this part number were not confirmed on the manufacturer's own pages, so none are listed here. Owners on user forums are divided. Many say a cold-air intake on a healthy WK2 mostly changes sound and looks, while others report better throttle response when the intake draws cooler air. The recurring forum caution is that over-oiling a cotton filter during cleaning can damage mass airflow sensors, so follow the manufacturer's cleaning guidance closely. Compared with a generic universal intake, this is a purpose-built kit for this specific engine.
Shoppers searching for a 2016-2022 Grand Cherokee WK2 3.6L cold air intake, a NextGen aluminum intake tube, or an oiled cotton filter replacement will find this kit fits those needs. The manufacturer's install guide describes a typical job of 60 minutes or less with basic hand tools. The work involves disconnecting the battery, unplugging the mass airflow sensor, removing the stock tube, and moving the MAF sensor to the new tube. Confirm your model year and engine before ordering.
The manufacturer's catalog lists this part number for the Jeep Grand Cherokee V6-3.6L F/I. Confirm any other application directly with the manufacturer before ordering.
Owners on user forums warn that over-oiling a cotton filter during cleaning can damage mass airflow sensors and gum up the intake butterfly. Apply a light, measured amount of the manufacturer's recommended oil and follow its cleaning instructions.
No. The 77-1572KS is a separately numbered K&N kit for the same engine, with its own instruction sheet. Make sure the instructions you use match MPN 70-1572.
The manufacturer's general install guide for its cold air kits describes a typical completion time of 60 minutes or less with simple hand tools. Start by disconnecting the negative battery cable, unplugging the mass airflow sensor, and disconnecting the EVAP and crankcase vent lines. Loosen the clamps on the stock tube at the throttle body and airbox, then remove it. Move the MAF sensor into the K&N tube using the adapter and gasket, seat the tube in the coupler at the throttle body, and secure the airbox. For the closely related 77-series kit on this engine, the manufacturer's sheet calls for a ratchet, 10mm socket, 4mm Allen, a 3/4-inch wrench, and a flat-blade screwdriver, and it includes removing the decorative engine cover and disconnecting the inlet air temperature sensor. Check whether those steps apply to your 70-series kit before starting.
