K&N BMW F90 M5 & F91 F92 F93 M8 S63 Engine High Flow Air Filters
Description
Unlock your BMW’s true performance potential with the K&N High-Flow Air Filters (33-3128), engineered specifically for the BMW F90 M5 and F91/F92/F93 M8 with the S63 4.4L Twin-Turbo V8 engine. Designed to replace your factory filters directly, these precision-built filters deliver measurable gains in horsepower, torque, and throttle response — all while providing superior engine protection and long-term savings.
Each filter is built using four layers of premium cotton gauze, treated with a specially formulated tacking agent to create an intricate filtration mesh capable of trapping up to 99% of harmful contaminants without restricting airflow. The result is cleaner, denser air entering your engine for improved combustion efficiency and sharper throttle response.
Manufactured to exacting standards, K&N’s filters feature rugged construction, a washable and reusable design, and a no-hassle lifetime limited warranty. They’re pre-oiled and ready to install straight out of the box — a simple yet highly effective upgrade that complements both factory and tuned applications.
