I really liked the idea of the oil catch can and was about to order one for my 2005 coupe. while at work on my tug i was looking for some air tools to order and i came across an air supply oil and water seprator. My brain went into overdrive. We had an old one as a spair and the fittings to make it work. It looks like it is a factory part after i installed it. The best part is you can see how much oil is in the canister and to clean it only takes a twist and pull it down.
