Universal Clamp-On by aFe®. These universal air filters are designed to provide performance and protection. They feature extra-deep pleats and special pleat geometry to maximize airflow and integral velocity stacks to accelerate flow with minimal aerodynamic loss. The pliable flange with integrated bumps ensures a tight, no-leak seal. There are numerous sizes available in your choice of filtering media.

aFe manufactures numerous sizes of these conical air filters for many applications. They feature 3 different types of filter media, and a full or modified integral velocity stack. The velocity stack increases the effective diameter of the intake tube; they flow more than standard filters but require a longer flange and wider filter base. The modified velocity stack allows for maximum airflow in limited base dimensions. They're used where space is a concern or where there is already a velocity stack at the filter tube transition. Many Pro 5R sizes feature an inverted filter top.
The Pro 5R filter media 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.
The Pro GUARD 7 filter media delivers increased airflow while providing the highest level of filtration efficiency available – 99.7%. The patented 7-layer progressive cotton/synthetic media in the Pro GUARD 7 consists of 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity.
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 and Pro GUARD 7, 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 Pro DRY S filter media combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 2 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.
The pleats 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 structures are made from 100% polyurethane, to withstand extreme engine temperatures.42.29 148.14
