i bought this to have as a spare. i plugged it in to make sure it works and it did. i put it in a box, put it up on the shelf and haven't touched it since. that was a year and a half ago. i sold the 912e and have no use for this anymore. if you have a 912e you know these are very hard to come by and are specific to that car.
air snorkel for 912e. looks like someone cut it but i don't know how much $50 shipped
