BMC Air Filter FB473/04 – High Performance Panel Filter – Porsche 997 Turbo/GT2/GT2RS/GT3RS

High-performance BMC FB473/04 washable panel air filter designed for Porsche 911 (997) Turbo and GT models. Direct OEM replacement delivering increased airflow, improved filtration, and long-term reusability.

Product Description

The BMC FB473/04 High Performance Air Filter is engineered to replace the restrictive OEM paper filter in select Porsche 911 (997) Turbo and GT models, improving airflow while maintaining excellent filtration efficiency.

Manufactured in Italy using multi-layer oiled cotton gauze, the FB473/04 allows significantly higher air flow compared to conventional paper filters while capturing particles as small as 7 microns. This improves engine breathing, throttle response and overall efficiency without compromising engine protection.

BMC’s Full Moulding technology creates a single-piece rubber frame without welded joints, ensuring a perfect seal inside the factory airbox and exceptional durability under high-performance driving conditions.

Unlike disposable paper filters, the FB473/04 is fully washable and reusable, making it a long-term performance upgrade for Porsche enthusiasts who want improved airflow and reduced maintenance costs.

Designed as a direct drop-in replacement, installation requires no modifications—simply remove the factory filter and install the BMC unit.
