After installing the lid. What do you guys do with the long hose that use to plug into the original lid? And what does it do? I notice it seems to suck air for a few minutes after starting the car and then stops.

Thank you for the help.

 

Its part of the AIR system. (emmissions stuff)

Put a filter in the the end and tuck it out of sight.

 

Unless it has recently changed, the only lid that has that provision is the SLP lid. All the other brands just supply a small filter to plug the hose with for 2000+ models.

 

Just had an slp lid for a 2001 ws6 installed and that year lid has the hole for the hose. 2000 and below dont have that hole on the slp lids

SLP lids are the only ones with the provision for the AIR hose.

If you don't have and SLP lid, most people put a breather filter on the hose and ty-wrap it to the radiator support.

Personally, I didn't like the way that looked so I cut the AIR hose about 2 inches from the AIR pump and stuck the breather filter on it there. That way it is still sucking filtered air, but you don't have this fugly hose strapped where it doesn't belong and looking out of place.
