Description
The BMW OEM Air Filter 13718577170 is the genuine original equipment manufacturer solution for high-capacity induction filtration, built strictly to the demanding specifications of BMW AG. Developed specifically to handle the massive volumetric air intake requirements of forced-induction six-cylinder engines, this premium filter utilizes a high-stability pleated element that maintains its structural integrity under intense turbocharger suction and heavy boost loads. The precise sealing perimeter prevents unmetered, raw bypass air from entering the combustion tract, ensuring that only clinically clean air reaches the cylinders. This aerodynamic efficiency guarantees optimal fuel atomization, protects the precision hot-wire elements of the Mass Air Flow (MAF) sensor, and prevents micro-scratching on the cylinder walls.
Vehicle Application Compatibility:
This genuine high-airflow engine air filter is engineered exclusively for luxury sports variants running the highly acclaimed B58 (3.0L TwinPower Turbo Inline-6) petrol engine found in these premium platforms driven across Bangladesh:
- BMW 3 Series (G20 / G21 Chassis): M340i / M340i xDrive (2019 – Present)
- BMW 4 Series (G22 / G23 / G26 Chassis): M440i / M440i xDrive Coupe, Convertible & Gran Coupe (2021 – Present)
- BMW Z4 Roadster (G29 Chassis): M40i (2019 – Present)
- Toyota GR Supra (A90 / A91 Chassis): 3.0L RZ / Premium Models (2019 – Present)
(Note: This filter does not fit the standard 2.0L 4-cylinder B48 engine trims like the 320i or 520i; it is dedicated strictly to the high-performance 3.0L 6-cylinder variants listed above).

Maintenance Tip from Oil House Bangladesh:
The engine air filter is the frontline defense for your high-performance turbocharger. In Bangladesh, where premium sports sedans navigate heavy highway dust, thick metropolitan construction smoke, and stop-and-go gridlock, the intake filter accumulates dirt rapidly. A restricted or generic air filter starving a twin-scroll turbo system causes immediate performance loss, noticeable throttle lag, and forces the turbocharger to work significantly harder, running hotter and risking premature bearing wear. When servicing this unit, always make sure the technician vacuums out any collected leaves, sand, or loose dirt from the bottom of the factory airbox housing before dropping in the new filter. For absolute powertrain protection and to maintain the violent acceleration of your B58 engine in local driving conditions, we strongly advise inspecting the air filter every 5,000 km and replacing it entirely every 10,000 km.
