Porsche The Cayman - Resonance intake manifold

Resonance intake manifold

The resonance effect, where the air mass inside the intake manifold is caused to oscillate, is used to improve air induction and, in turn, to optimise the formation of the fuel/air mixture. In the Cayman S, the manifold is also equipped with a switchable resonance valve.

The results are high torque, a uniform torque curve and high power output. The sound produced is characteristically resonant and deep.
