duncan Posted December 16, 2020 Share Posted December 16, 2020 From the small print in the 987.2 Technical Appraisal by Porsche see post in “Technical FAQ & How to” below : . . “Air cleaner All new Boxster and Cayman models are fitted with the same air cleaner as their previous models. On the Boxster models only, the size and position of the opening to the Helmholz resonator (H) have been modified at the air cleaner output in the intake area for the intake system. This improves the intake noise, in particular on the "open" Boxster models with minimal intrinsic insulation from the roof construction or when driving with the top down” . . . And their you have it for 987.2 models: Caymans are more powerful than Boxsters, Boxsters are noisier than Caymans, 1 Link to comment Share on other sites More sharing options...
