BMC Replacement Air Filter – High-Performance OEM Airbox Upgrade

Fits Audi A4, A5, RS4, S4, RS5, S5 & Q5 (Various Years)

The BMC Replacement Air Filter is a high-performance panel/cylindrical air filter designed to be installed directly into your vehicle’s original factory airbox, replacing the OEM paper filter. Engineered with advanced materials and motorsport-derived technology, this filter delivers increased airflow while maintaining superior filtration efficiency for long-term engine protection.

Unlike standard OEM paper filters that typically trap particles down to 10 microns, BMC air filters are capable of containing impurities as small as 7 microns. This balance of higher airflow and finer filtration helps improve throttle response and overall engine efficiency without compromising reliability.

Advanced Filtration Technology

• Multi-layered cotton gauze filtration media
• Pre-oiled with low-viscosity oil for optimal airflow
• Epoxy-coated alloy mesh protects against fuel vapors and oxidation
• Designed to increase airflow compared to OEM paper filters

BMC filters are manufactured using an exclusive Full Moulding system, allowing the iconic red filter to be produced from a single mold with no welded joints. This construction eliminates weak points, reduces the risk of breakage, and ensures consistent sealing inside the airbox.

Durable & Long-Lasting Design

• High-quality rubber frame with excellent elasticity and adhesion
• Maintains perfect fit across various airbox shapes
• Resistant to heat, fuel vapors, and air humidity
• Built for long service life under demanding conditions

Performance Testing (Illustrative)

Airflow testing comparing a BMC air filter to a standard OEM paper filter demonstrates improved airflow under identical conditions:
