BMC Air Filter FB798/20 – Porsche 991 Turbo / Turbo S (991.1 & 991.2)
High-performance BMC FB798/20 washable panel air filter designed as a direct OEM replacement for Porsche 911 Turbo and Turbo S models (991 & 991.2). Improves airflow, filtration efficiency and engine responsiveness while remaining fully reusable.
Product Description
The BMC FB798/20 Performance Air Filter is engineered to replace the factory paper air filter in Porsche 911 Turbo models with a high-flow, reusable alternative designed for both road and track use.
Manufactured in Italy using multi-layer cotton gauze soaked in low-viscosity oil, the FB798/20 allows increased airflow while maintaining exceptional filtration efficiency. This construction captures particles as small as 7 microns, providing superior engine protection compared to standard paper filters.
BMC uses a Full Moulding production process, creating the filter in a single mould without welded joints. This results in improved durability, optimal sealing in the factory airbox and long-term reliability under high temperatures and engine loads.
Unlike disposable paper filters, the FB798/20 is washable and reusable, allowing it to be cleaned and re-oiled using the BMC regeneration kit. This provides a long-term performance upgrade that can last the lifetime of the vehicle.
Designed as a direct drop-in replacement, installation is simple and requires no modifications.
