Double Flow Distribution Pipe

2446 - Intake System

Double Flow Distribution Pipe










The new engines are equipped with a new intake system featuring a double flow distribution pipe. With this new system, the distribution pipe flap in the intermediate pipe connecting the two intake air distributors is closed in the low rpm range. The distribution pipe is designed with a partition wall running along its length (between the electronic throttle and the distribution pipe flap in the intermediate pipe), as a result of which the 6-cylinder engine behaves like two 3 cylinder engines running in parallel in the low rpm range (when the distribution pipe flap is closed), leading to an improved torque characteristic in the low rpm range.

Boxster (987) - The distribution pipe flap is opened in the two rpm ranges from 3100 to 5000 rpm and from 5600 to 7200 rpm.

Boxster S (987) - The distribution pipe flap is opened in the two rpm ranges from 3500 to 4700 rpm and from 5400 to 7200 rpm.
