BMC 2019+ Audi A6 (4A/C8) TFSI RS6 Replacement Panel Air Filter

BMC Air Filter for 2021+ BMW M3 & M4 (G80/G82) | High-Flow Drop-In

Upgrade your 2021+ BMW M3/M4 (G80/G82) S58 engine with BMC Replacement Panel Air Filters. Superior filtration down to 7 microns & increased airflow.

Engineered in Italy for maximum performance, the BMC Replacement Panel Air Filter set is an essential upgrade for the 2021+ BMW M3 (G80) and M4 (G82/G83) equipped with the 3.0L Twin-Turbo S58 engine. Designed as a direct drop-in replacement for the restrictive factory paper filters, this set delivers enhanced airflow straight to your twin turbos while offering exceptional engine protection.

BMC utilizes a multi-layered cotton gauze material treated with low-viscosity oil, encased in an epoxy-coated alloy mesh to shield against moisture and petrol fumes. Thanks to BMC’s signature single-mold "Full Moulding" manufacturing process, the durable red rubber housing eliminates welded joints to prevent breakage or tearing under high vacuum pressures. Unlike disposable OEM paper filters, BMC filters are washable and fully reusable, making them a permanent performance solution for your BMW.

Best Uses

1. OEM+ Performance Upgrade: Ideal for owners wanting increased horsepower, sharper throttle response, and subtle turbo spool sound without swapping out the factory airbox setup.
2. Tuned & Modified S58 Engines: Excellent supporting mod for vehicles running ECU tunes, downpipes, or upgraded exhaust systems that demand extra airflow.
