I've got three GM LT1 Caprice 3" MAFs. The exterior of the MAF housings have been cleaned up nicely since these pics. The housings have been lightly sanded, airbrushed with OEM BMW light metallic paint, and cleared to a glass finish. The paint used is the same we use at work for BMW wheel restoration. You can have one for $60 shipped. I can post some updated pics tomorrow if you want to see.
