Weapon-R Secret Weapon Replacement Air Intake Filter

The Weapon-R Secret Weapon Replacement Air Intake Filter is a performance foam air filter for aftermarket intake systems. Weapon-R built it to increase airflow and air speed into the engine while still filtering out dirt. Use it as a replacement air intake filter, or as an upgrade over a stock paper or cotton element.

Key Features:

• Dense polyurethane foam element: Gives high airflow with effective dirt filtration.
• Open-cell foam design: Air flows around captured dirt, so the filter keeps good airflow as it collects debris.
• Velocity stack design: The CAD-designed, flow-bench-tested velocity stack is meant to raise airflow, air speed and air mass into the engine.
• Serviceable construction: The filter can be taken apart so the foam element can be cleaned, then reassembled.
• Protective frame and grid: A tough frame and a grid protect the foam element.
• Ready to install: The foam element does not need oiling.

Weapon-R says foam filters can flow up to 80% more air and filter dirt better than conventional cotton filters. The Secret Weapon filter comes in several inlet sizes and lengths, so you can match it to your intake setup.
