Product Description

The Weapon-R 710-110-112 Secret Weapon Air Filter is a universal high-performance intake filter engineered to maximize airflow while maintaining strong filtration efficiency. Designed with advanced polyurethane foam filtration and an integrated velocity stack, this filter helps improve intake airspeed and airflow volume entering the engine. The result is improved throttle response and more efficient engine breathing for performance intake systems.

Unlike conventional cotton filters, the Secret Weapon filter uses open-cell foam technology that allows air to continue flowing around trapped debris. This design helps maintain consistent airflow even as the filter collects contaminants, reducing restriction and preserving performance over time. The CAD-designed velocity stack has been flow-bench tested to increase air mass and intake efficiency.

The filter features a durable gunmetal mesh cage that helps maintain filter structure under high airflow conditions while protecting the foam element. With a 4-inch inlet diameter and a tall 10-inch body, the Weapon-R Secret Weapon filter is ideal for custom intake setups, turbocharged applications, and high-performance cold air or short ram intake systems that require a large-capacity universal filter.
