Air Cleaner







The air cleaner housing and the air cleaner element were newly developed for the new 911 Turbo. The air cleaner housing was lined inside with foam in order to obtain an optimum intake sound. It was possible to reduce the intake resistance and optimize the charge cycle by way of the 2-channel intake via the rear lid, the new air cleaner element and two separate intake pipes to the turbochargers on the left and right.

In addition, it was also possible to reduce the frequency of cleaner replacement. The air cleaner element now has to be replaced only every 40,000 miles (60,000 km) or after 4 years. The top part of the new air cleaner (housing) has been provided with a design cover made of aluminium to visually upgrade the engine compartment. This cover is embossed with the logo "VARIABLE TURBINE GEOMETRY".
