BMC 2017 BMW 3 (F30/F31/F80) M3 CS Replacement Panel Air Filter (Full Kit)

BMC Air Filter Kit for 2017 BMW M3 CS (F30/F31/F80) | Performance Panel Filters

Upgrade your 2017 BMW M3 CS (F30/F31/F80) with the BMC Replacement Panel Air Filter Full Kit. Boost airflow, improve throttle response, and enjoy washable, reusable performance.

Engineered directly from Formula 1 racing technology, the BMC Replacement Panel Air Filter Full Kit (FB647/20) provides an ultimate drop-in performance upgrade for the 2017 BMW 3 Series M3 CS (F30/F31/F80). Designed to replace the restrictive factory paper air filters, this full kit supplies both necessary filters to fit the S55 twin-turbo engine's dual airbox configuration perfectly.

BMC constructs its filters using a signature "Full Moulding" process—a single-piece production technique that eliminates welded joints to prevent stress fractures and seam failure under high-boost conditions. The filtering element features a multi-layer cotton gauze soaked in low-viscosity oil and protected by an epoxy-coated alloy mesh, defending against fuel fumes, moisture, and oxidization. By trapping contaminants down to 7 microns—compared to the standard OEM 10-micron threshold—BMC maximizes clean air throughput without sacrificing engine protection. The result is sharper throttle response, enhanced induction sound, optimized combustion efficiency, and reusable convenience over the lifespan of your vehicle.

Best Uses

1. Direct OEM Airbox Upgrade: Simple drop-in replacement requiring no custom piping or modifications.
2. Performance & Track Driving: Maximizes twin-turbo S55 airflow efficiency during high-RPM and high-heat conditions.
3. Tuned Applications: Ideal supporting mod for ECU remapped, stage-tuned, or upgraded exhaust vehicles needing increased air intake.
4. Eco-Friendly Long-Term Maintenance: Replaces disposable OEM paper filters with a washable, long-lasting performance alternative.

Features

1. Full Moulding Technology: Formed from a single continuous mold with no weak welded joints for maximum durability and durability against cracking.
2. Multi-Layer Oiled Cotton Gauze: Uses low-viscosity oiled cotton layers wrapped in epoxy-coated alloy mesh to shield against humidity and fuel vapors.
3. Micro-Particle Filtration (7 Microns): Filters out contaminants down to 7 microns, outperforming traditional paper OEM filters (10 microns).
4. Precision Drop-In Fitment: Engineered specifically to mirror the original BMW F80 S55 airbox dimensions for a seamless 100% bolt-on installation.
5. Washable & Regenerable: Fully cleanable using BMC air filter cleaning kits, eliminating the need to buy replacement paper filters.

Benefits

1. Improved Airflow & Power: High-flow cotton material increases intake volume to help unlock engine horsepower and torque potential.
2. Sharper Throttle Response: Minimizes intake restrictions for faster turbo spooling and immediate power delivery when pressing the accelerator.
3. Superior Engine Protection: Advanced filtration captures finer abrasive dust particles before they enter the intake manifold, extending engine life.
4. Cost-Effective Lifetime Value: Reusable design saves money on routine service replacements across the entire lifespan of the vehicle.
5. Enhanced Intake Sound: Unlocks a subtly throatier, more responsive turbo induction noise under acceleration.
