Spectre Performance air intake for 1991-2001 Jeep Cherokee XJ 4.0-liter air intake

Spectre Performance air intake for 1991-2001 Jeep Cherokee XJ 4.0-liter inline six, number 9051

Jeep has used the Cherokee name for several models over the last forty years. It began with the full size Jeep Cherokee SJ in 1974 and at the same time coined the term Sport Utility in the 1974 Cherokee sales brochure. In its most current rendition the Jeep Cherokee KL is a mid-size crossover SUV. While every iteration of the Jeep Cherokee has its merits, the Jeep Cherokee XJ produced from 1984 to 2001 has been perhaps the most popular Cherokee and had the most profound impact on the off-road community. The Jeep Cherokee XJ has a legion of loyal fans and remains a popular choice for off-road enthusiasts.

Spectre Performance Jeep Cherokee XJ air intake suplies the 4.0L engine with more air

The Spectre Performance Jeep Cherokee XJ air intake will supply the 4.0L engine with more air and is designed to improve performance for on-road or off-road situations

The venerable 4.0-liter AMC 242 inline 6-cylinder engine was first introduced into the list of Jeep Cherokee XJ options for the 1987 model year. This bullet proof engine continued to be the power plant option of choice until the Cherokee XJ was discontinued in 2001. For those die-hard Jeep Cherokee XJ owners looking to add more power, whether for daily driving or conquering the trail, Spectre Performance has an air intake system for 4.0-liter L6 powered Jeep Cherokee XJ models.

Spectre Performance engineers built an intake, number 9051, specifically to fit the 1991-2001 Jeep Cherokee XJ 4.0L inline six

Spectre Performance engineers decided to build an intake that’s equally functional as the Cherokee XJ 4.0L it will be installed on. Using a polished aluminum air intake tube, Spectre Performance oversize synthetic air filter, and an application specific air filter heat shield, fresh air is drawn into the Jeep Cherokee XJ intake where the factory air box was. The Spectre Performance Jeep Cherokee air intake will supply the 4.0L engine with increased airflow for improved performance and better acceleration.

Dust filtration and engine protection comes from a Spectre High Performance Racing (HPR) air filter HPR9606 clamped to the aluminum air intake tube. Spectre HPR air filters are specifically designed to outperform an ordinary paper air filter by providing increased airflow for improved performance without sacrificing engine protection. Spectre HPR performance air filters are manufactured using high quality materials throughout including a pre-dyed synthetic filter media that will not fade, top quality urethane, and steel mesh. Spectre High Performance Racing air filters are pre-oiled and ready to use. These air filters can be serviced when dirty, using part number 884820, and used again.
