Hi All,

I installed the engine sound package airbox cover today. I saw that there is an additional hole, which was covered on the "old one" with a simple rubber plug.
Here is a picture from another thread that discussed the topic, but didnt come to a conclusion:




Question:
I understand for manual transmission cars, it is important to connect the suction from the gearbox. However for Tiptronics, I assume I can simply leave the plug removed to allow more air to get in.

Correct?

Thanks,

It sucks air from the clutch and som people recomend that You disconnect it in otder to prevent Your engine from inhaling clutch dust!

Mine is still connected, I trust the German engineers!

Hi,

yes, but on Tiptronic cars, my understanding is, there is nothing connected, you simply have the rubber in the hole!

+1 !! My Tip has the plug in place. Can't imagine the factory would design the air box to be so close to the margin on air-flow that another small (unsightly if not covered, IMO) open hole could ever provide any induction benefits.

And if I had a 6-speed, I think I'd trust the air filter to catch any stray clutch dust. - instead of letting more of it accumulate in the trans.

I removed the transmission clutch vent from the airbox and purchased the plug from Sunset. My air filter last so much longer now. My understanding it is just there for meeting air quality regulations in some countries.

Think of the tens of thousands of manual transmission 911's that didn't have the clutch vent tube. Ever heard of a clutch failing because of accumulated clutch dust? They usually fail because of a worn disc, bad throw-out bearing or a seal going bad. When clean air means everything to your engine, who would want to suck clutch dust into it?

Appears to be a good bit of prior discussion on this topic......https://rennlist.com/forums/993-foru...he-intake.html

Pulled my clutch vent pipe out when I did the r/h plug bank and left it off as many have done. It's the only Porsche that uses it. Outlet on clutch housing covered with wire mesh and airbox bung fitted along with with techtronic engine tin. Flexy pipe had disintegrated many moons ago so probably non funtional for ages.
