K&N air intake system for 1996-2001 Jeep Cherokee

Boost performance of 1996-2001 Jeep Cherokee models powered by the venerable 4.0L straight-6, originally designed by AMC in 1964, with a K&N performance air intake system

First introduced by American Motors back in 1984, the Jeep Cherokee helped to usher in the modern era of SUV's. By the early 90's, it had become one of the most popular and powerful midsize Sport Utility Vehicles on the market. Suburbanites were ditching their minivans and flocking en masse to the SUV, so to help it keep pace with the competition; Jeep significantly updated the Cherokee in 1996 and 1997. They did however; keep the venerable 4.0L straight-6, which was originally designed by AMC back in 1964. Thanks to fuel injection, and a host of other modern improvements, the Jeep Cherokee 4.0L made a very adequate 190-hp and 225 lb-ft of torque. But owners can now enjoy more performance from their 1996-2001 Jeep Cherokee, thanks to a K&N FIPK Air Intake System.

Designed specifically to fit the 1996-2001 Jeep Cherokee 4.0 H.O. inline-6, the K&N FIPK Air Intake System, number 57-1518, is able to deliver more horsepower and torque, by reducing the airflow restrictions between the air filter and the intake manifold. A high-volume conical K&N air filter fits in place of the stock air box, and feeds significantly more air to the engine through a special rotationally molded intake tube. This low-restriction intake tube is made from rugged High Density Polyethylene (HDPE), so you won't have to worry about it on the trail. HDPE can also help to prevent engine heat from warming the air before it reaches the throttle body. The shape of the tube itself has been engineered to reduce air turbulence and deliver more air to the throttle body, faster.

To ensure a constant supply of cool air, the 1996-2001 Jeep Cherokee K&N FIPK Intake System comes with a special heat shield that protects the air filter from engine bay heat. The high-flow K&N air filter is not only washable and reusable but it is backed by a 10-year/million mile limited warranty. The oiled cotton gauze filter media is also able to provide much better air flow than a synthetic or stock paper air filter, without sacrificing engine protection. So no matter how much dust you kick up on the trail, your engine will be protected.
