This is a listing for unused auto parts purchased from Burger Motorsports in 2022 by my son who at the time owned a 2008 535XI.  For some reason mechanic wasn't able to install it so these parts have been stored here in my garage which is why they're dusty but still new.  Trying to downsize which is why this is being sold.  In addition to the High Flow Silicone Inlets, there are two filters.  Unfortunately I don't know anything else about it only know that he paid $370.00 for these so hopefully by looking at the photos you'll be able to see whether they'll work for you.
