Sport Air Filter 991.1 and 991.2 Turbo / S - BMC

Description

BMC Sport Air Filters were originally developed in association with the Ferrari F1 team. BMC is one of the most recognized brands in the automotive industry and is the most successful filter in many types of racing.

OEM filters only require a total particle filtration efficiency up to a minimum size of 10 microns. OEM air filters function primarily to protect the engine, so they are cost effectively produced in paper. Paper filters have high resistance to airflow that reduces the inlet pressure and consequently engine performance.

A BMC sport filter contains an outer epoxy coated alloy mesh with internal layers of cotton gauze that have been immersed in a low viscosity oil. That technique ensures protection from fuel fumes and from oxidation due to humidity in the air. It also ensures superior air permeability and more efficient filtration down to 7 microns. BMC filtration systems yield more engine performance, both in terms of power and torque without compromising reliability.

Please Note: A BMC sport filter is a direct replacement for the factory air filter. Also, there is a lot of misinformation about sport filters fouling mass air flow sensors (MAF's). In the manufacturing process the exact amount of oil is used, and we have never experienced this with a new filter. In our experience, fouled MAF's are attributed to individuals over oiling their filters after cleaning.
