Therefore the thread/discussion below may be of interest.

Basics of Intake Length vs Torque-HP

So we all know long intake pipe means better low end torque-hp & short intake pipe means better torque-hp at high RPM's.

I once tried some driving with the air filter open and just bungied down, I did love the sound. However the filter got dirty quickly and the seal along the edge was not so great after a while. This was on a CIS 911, not a Boxster just to clarify.
