The aFe Pro 5R air filter was designed to provide the maximum airflow possible, to enable your engine to make the most horsepower and torque. But aFe didn't achieve this by ignoring engine protection. The Pro 5R outperforms most other cotton gauze air filters with a 98.6% efficiency rating.

The increased airflow and high filtration capability are the result of the Pro 5R's construction. It's made of 5 layers of progressively finer medical-grade cotton gauze. Competitors use constant size mesh gauze in their filters, which creates voids/openings that can allow dirt to pass through. As the progressively finer layers of gauze are stacked in the Pro 5R, the randomness of the openings increase, minimizing spaces with no filter media. Dust accumulates on multiple layers, increasing overall dust holding capacity and filtration efficiency.

The pleats in the Pro 5R are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity.

The sealing surface and supporting structure of the Pro 5R are made from 100% polyurethane, to withstand extreme engine temperatures. Flat panel filters are constructed with 4 sides, not just 2, for added rigidity and seal support, and feature a progressive bump seal to ensure an airtight seal.

The Pro 5R isn't only less restrictive and more efficient, it's also more economical. Under normal driving conditions it won't need servicing for 25,000 to 30,000 miles. Since a typical OEM paper element should be replaced every 15,000 miles, the Pro 5R will pay for itself before the first service is required. And since the Pro 5R can be washed and reused repeatedly, you'll never have to buy another air filter, ever.

Direct factory replacement Pro 5R air filters are backed by a limited lifetime warranty. Universal clamp on filters have a 2-year warranty while racing filters have a 1-year warranty.
