I'm a new Boxster owner - and really appreciate all of the great info on this forum.

I read about an updated version of the coolant cap (996 106 447 04), so I decided to replace the stock one in my car (996 106 447 00). I was getting a slight smell of coolant in the trunk and I could also hear a slight hiss/gurgle sound if I put my ear to the cap once the car was fully warmed up.

Here are some pictures for comparison in case anyone wants to see how the new cap has been improved... The old version is on the right.

Hopefully this update helped to avoid a trunk full of coolant!
