MMX Performance’s Blue Cotton drop-in panel filters for F-chassis and G-chassis BMW 1 / 2 / 3 / 4 (B48, B58) improve airflow, throttle response, and induction tone while maintaining OEM fit and filtration. Washable and reusable, it’s a warranty-friendly upgrade — MMX testing shows up to +15Nm on a stock B58.
MMX Performance’s Blue Cotton Replacement Panel Air Filters offer a simple, warranty-friendly upgrade for F- and G-chassis BMW 1, 2, 3, and 4 Series models equipped with B48 2.0L four-cylinder or B58 3.0L six-cylinder engines. Engineered as a direct drop-in to the OEM airbox, MMX’s multi-layer cotton gauze element reduces the inherent restriction of factory paper filters to improve engine breathing, yielding crisper throttle response, enhanced induction character, and efficient airflow that can translate to measurable performance benefits. In MMX’s testing, a standard B58 engine gained up to an additional 15Nm of torque — a small but worthwhile improvement — while maintaining excellent filtration. Built to OEM standards for fit, materials, and durability, this washable, reusable filter installs like a factory part and is designed to last like one, providing an easy, maintenance-friendly path to consistent, repeatable gains across a wide range of applicable Fxx and Gxx models.
