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 didnt 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 5Rs construction. It’s made of 5 layers of progressively finer medical-grade cotton gauze.
The Pro DRY S filter 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 hasnt been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.
The Pro GUARD 7 air filter 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.
Pro Guard 7 air filter media is constructed using 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity. The result is high-performance air flow with the filtration efficiency of a heavy-duty filter. This media is so unique it was granted US patent 6,811,588 (the only filtration media of its kind to be granted a U.S. patent).

100% polyurethane construction withstands extreme engine temperatures
Built-in expanded metal (select filters) prevents collapse under high boost pressures
Pro GUARD 7s 2 extra layers of progressive synthetic media provide the highest engine protection possible
No other performance filter media can match the engine protection of aFe Pro GUARD 7
The Momentum HD is designed around a massive 1,000cfm performance 360 degree radial flow air filter with 10-layers of progressive cotton media providing 99.59% cumulative efficiency (independently tested). The unique air filter to housing interface (patent pending) allows for maximum filter size which increases the available air volume while simplifying the installation process. The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse.
