Air Cleaner Housing: Description and Operation

2425 Air Filter Housing With Sound Openings







To avoid a possible intake of warm air from the engine compartment even under critical engine operating conditions (e.g. high ambient air temperature), the sound openings on the underside of the air filter housing have been modified. By using openings with a large surface area with inserted, almost airtight fabric, the intake of warm air from the engine compartment is nearly completely prevented while the intake sound typical for Porsche is retained.

911 Carrera (997) Air Filter Housing

The construction of the air filter basically corresponds to that of the 911 Carrera (996) from model year 2004. The redesign of the scoop and the upper part of the air cleaner with the integrated "PORSCHE 3.6" logo as well as the rerouting of the hoses and lines are essential elements for the upgrading of the engine compartment with an attractive look.
