Performance Air Filter for BMW X3 / X4 / X5 / X6 / X7 (2017+) 1.6L 2.0L 3.0L

High-Velocity Filtration for BMW G-Chassis B47, B48, B57, & B58 Engines

Who It’s For: Engineered for BMW G01, G02, G05, G06, and G07 owners who want to optimize the volumetric efficiency of their turbocharged powerplants, ranging from the efficient B48 inline-four to the powerhouse B58 straight-six.

The Symptom: The factory air intake system on modern BMW SAVs is designed with a heavy bias toward sound suppression and long service intervals. This is achieved through a thick, restrictive paper element that creates a significant pressure drop across the filter media. When you’re trying to move a heavy chassis like the X5 or X7, that restriction translates to a slight hesitation in boost threshold and a stifled engine note.

The stock paper fibers eventually clog, forcing the turbocharger to work harder and generate more heat just to pull the required air volume into the combustion chamber.

The Engineering Fix: This BMC performance filter replaces the restrictive paper with four layers of low-viscosity oil-soaked cotton gauze. By utilizing the physics of impingement rather than a simple mechanical barrier, this filter allows for a much higher CFM (Cubic Feet per Minute) while actually improving filtration density down to 7 microns.

The "Full Moulding" construction creates a single-piece frame without welded joints, ensuring a perfect seal against the airbox walls. This prevents "dirty air" bypass and ensures that every ounce of air entering the engine is filtered and flowing at maximum velocity.

Why Mechanics Choose This Kit

• Enhanced Induction Efficiency: By reducing the intake resistance, the B58 and B47/B57 turbochargers can reach target boost pressures more quickly, sharpening throttle response during low-end acceleration.
• Industrial-Grade Construction: Features an epoxy-coated alloy mesh that protects the cotton filtration media from petrol fumes and oxidation, ensuring the pleats stay uniform under high vacuum.
• Sustainable Performance: Unlike disposable OEM filters, this unit is fully washable and regenerable, making it the last air filter your BMW will ever need.
