AFE 21-91129 QUANTUM INTAKE REPLACEMENT AIR FILTER W/ PRO DRY S 5"F X (10" X 8.75")B (QTM) X (6.75" X 5.5")T (INV) X 9"H IN.

The aFe 21-91129 Quantum Intake Replacement Air Filter is engineered to elevate your vehicle's performance while ensuring a seamless fit with Quantum Series cold air intake systems. This innovative filter features a unique patent-pending integrated design that combines the filter and housing using four captive screws. This not only secures a positive surface area seal but also simplifies the installation process, allowing for quick changes when needed.

Constructed with the advanced Quantum Pro DRY S filter media, this filter is perfect for drivers who frequently navigate normal to dry, dusty conditions. The oil-free, 360-degree radial flow design utilizes three layers of progressively finer synthetic media, optimizing airflow while providing superior filtration. This ensures both enhanced performance and ease of maintenance, as you won’t have to deal with messy oil coatings typically associated with traditional filters.

The lightweight injection-molded top and base of the Quantum Pro DRY S contribute to its durability and rigidity, ensuring it withstands the rigors of varying driving conditions. An innovative built-in, 3-angle velocity stack enhances airflow, promoting smoother and more efficient engine performance.

This air filter not only champions functionality but also embodies convenience with its user-friendly design. The inclusion of captive screws minimizes the risk of lost hardware, allowing for a secure installation that won’t come loose during use.

With the aFe 21-91129 Quantum Intake Replacement Air Filter, you can enjoy the confidence of knowing your engine is working with an air filter designed for optimum performance, reliability, and ease of use. Upgrade your vehicle's air intake system with this exceptional filter and experience the difference in performance and efficiency.
