Construction & Design

The Magnum FLOW Pro 5R Air Filter is crafted from premium materials engineered to withstand harsh operating conditions. Its filtration media consists of five layers of oiled cotton gauze, each layer progressively finer to trap particles effectively while maintaining unrestricted airflow. This oiled cotton gauze media enhances filtration efficiency without compromising engine breathing.

The filter frame is molded from 100% polyurethane, providing a durable yet flexible structure that resists cracking and deformation over time. The precision-engineered urethane bump seal creates a consistent, airtight connection with the factory airbox, ensuring that all incoming air passes through the filter element for maximum engine protection.

Performance & Sound

Replacing the restrictive stock paper filter with the aFe Magnum FLOW Pro 5R allows your Jeep’s engine to breathe more freely, resulting in improved throttle response and a modest increase in horsepower and torque. While this air filter does not alter exhaust sound, the enhanced airflow supports overall engine efficiency and performance, making it an excellent upgrade for both street driving and light off-road adventures.

Installation & Fitment

Installation is straightforward and requires no special tools or modifications. The Magnum FLOW Pro 5R Air Filter is designed as a direct replacement for the factory air filter in Jeep Cherokee XJ and Comanche MJ models from 1987 to 2001 with 2.5L and 4.0L engines. Simply remove the old air filter, insert the aFe filter into the stock airbox, and reinstall the airbox cover. Regular maintenance involves cleaning and re-oiling the filter according to aFe’s recommended service intervals to maintain optimal performance and longevity.
