Air Cleaner Housing: Description and Operation

2425 - Air Filter Housing







The air filter housing and the air filter have been completely redesigned. Flow optimization measures and the resultant reduction in counterpressure in the intake duct are instrumental to the improvement in performance. The increase in the air filter element's surface area to 14.5 sq.ft. (1.35 m2) (as compared to 6.1 sq.ft./0.57 m2 on the previous Boxster 986) leads to a reduction in the specific load on the air filter, as a result it has been possible to extend the change interval to 40,000 miles (60,000 km) or every 4 years.
