I purchased this a few years ago from an unlucky 318tier who had his car written off.
I was never able to install it on my 318ti, one of those projects that never happened. I am selling my 318ti, so also need to sell this part.
The previous owner claimed it had about 15k miles on the supercharger. It spins smoothly and freely. It has been boxed with the ports taped over since it arrived.
It is missing a few parts, noted below. Attached to this post is a PDF of the parts list from the manual so you can identify them. It also comes with a few "bonus" parts
The missing parts are: B2-0019 AFM Support Bracket B2-0013 MAF Support Bracket B0-0009 Idler Bracket B0-0013 Throttle Cable Radiator and PRV Hose
Bonus parts: Mass Air Flow Sensor Fuel rail with all injectors
