BMC Air Filter FB798/20 (Porsche 911 (991/991.2) Turbo & Turbo S 3.8 L H6)

High‑Performance Panel Filter for Porsche 911 Turbo (991 & 991.2)

The BMC Air Filter FB798/20 is engineered as a direct-fit, high-flow panel replacement for Porsche 911 Turbo and Turbo S models built on the 991 (2013–2016) and 991.2 (2016–2019) chassis with the 3.8 L H6 engine. It installs easily into the factory airbox without modifications.

Constructed with BMC’s motorsport-grade full‑moulding process, the FB798/20 air filter delivers enhanced airflow while capturing fine particles down to 7 microns—exceeding the filtration capability of OEM paper filters (~10 μm). The result: sharper throttle response, potential power gains, and improved long-term engine protection.
