Performance Air Filter for Jeep Wrangler YJ 2.5 / 4.0, CJ5, CJ8 (1985-1995)

Maximum Induction Efficiency for the Jeep AMC 150 Four and 242 Straight-Six Engines

Who It’s For: Engineered for Jeep CJ and Wrangler YJ owners running the legendary AMC 150 (2.5L) or the high-torque AMC 242 (4.0L) powerplants who are tired of the stock sluggishness during acceleration and off-road crawls.

The Symptom: The factory intake system on these classic Jeeps was designed with a heavy bias toward silence and basic dust protection, often at the expense of flow velocity. The restrictive OEM paper element creates significant static pressure, forcing the engine to work harder just to breathe, which results in a "lazy" throttle feel and a noticeable drop-off in the upper RPM range. For the 2.5L 4-cylinder especially, every CFM of airflow matters when trying to maintain highway speeds or navigating steep inclines.

The Engineering Fix: This high-performance upgrade replaces the dense paper media with a multi-layered, low-viscosity oil-treated cotton gauze. By utilizing a "Full Moulding" system, the filter is constructed from a single piece with no welded joints, ensuring total structural integrity and preventing unfiltered air bypass. This design smooths the fluid dynamics within the factory airbox, allowing for higher oxygen density and superior filtration down to 7 microns—surpassing the 10-micron standard of typical factory filters.

Why Mechanics Choose This Kit

• Optimized Volumetric Efficiency: By reducing intake restriction, we allow the AMC 150 and 242 engines to reach their peak volumetric efficiency sooner, providing sharper throttle snap and improved torque delivery.
• Superior Filtration Chemistry: The combination of epoxy-coated alloy mesh and oil-treated cotton gauze captures finer particulates while resisting the corrosive effects of fuel vapors and humidity.
• Induction Resonance: Eliminating the restrictive paper barrier allows for a more pronounced and aggressive induction growl without the need for a loud, exposed open-air intake.
