The K&N 33-5077 is a drop-in replacement air filter for the 2018 Jeep Grand Cherokee with the 6.2L V8 gas engine, as the manufacturer lists it for the 2018 Jeep Grand Cherokee IV 6.2L V8 gas application under part number 33-5077. It is meant to sit inside the factory air box in place of the stock element. Its main advantage over a disposable paper filter is that the air box, intake hardware, and sensors stay as they are from the factory. The manufacturer's installation sheets for its drop-in filters say the filter is a direct replacement and no modification is required. That makes this a practical upgrade for owners who want a reusable filter for a 6.2L Grand Cherokee without fabricating a cold-air intake, which is searched as a 2018 Grand Cherokee 6.2L drop-in air filter or K&N 33-5077 replacement.

This is an air box job rather than an intake conversion. Per the manufacturer's drop-in instructions, remove the stock filter, clean the sealing surfaces of dust and debris, and seat the K&N with its "this side up" engraving facing up. The K&N filter only fits in one direction. The manufacturer's hints also note that some K&N air filters need to be installed into the air box lid first, so hold the filter in place with your fingers while you reinstall the lid. If the lid is tight, disconnecting the air intake tube from the air box lid can make it easier to maneuver the lid.
