The Airaid 721-476 Premium Filter is a high-flow replacement air filter designed to support improved airflow for automotive engine applications. Its universal clamp-on design makes it suitable for custom intake setups and for upgrading compatible intake systems from other brands. This performance filter is engineered for enthusiasts seeking a durable, efficient filtration solution without replacing the entire intake system.
Multiple layers of filter media work with Airaid’s advanced filtration technology to help capture dirt and airborne particles effectively. The design provides a balance of airflow and filtration that ordinary cotton-gauze performance filters may not offer. Depending on the vehicle, intake configuration, and overall engine setup, improved airflow may support increased horsepower and torque. Always verify fitment and intake requirements before installation.
Airaid Premium Filters are proudly designed and manufactured in the USA using premium materials and advanced production standards. The 721-476 filter is intended for universal automotive applications and is available in a variety of shapes and styles across the Airaid product line. An optional Airaid AIR-799-472 Air Filter Wrap is associated with this filter and may provide an additional layer of protection in dusty or demanding environments. This product is not CARB approved and may not be legal for use on pollution-controlled vehicles in certain areas. It also carries a California Proposition 65 warning.
