Project 718 Cayman T: Part 8 – BMC Air Filter

I just had to show the components making up the chassis brace. That top piece looks to just be a chunk of billet machined aluminum which is not a cheap way to make parts. I think the main cross brace is an extrusion that is bent to shape. I bet the jigs for holding the pieces for welding are fun.

Yes, more foam underneath the side cubby panels.

I cut myself a tool access slot into the carpet cover so I could get a torx bit straight onto the fastener. I suppose Porsche makes maintenance require a bazillion steps so they can charge you a ton of money on service. For example, I’ve seen people pay $600-$700 for an oil change at the Porsche dealership for the 718. I just saw someone got quoted $340 for the engine air filter change.

    1. Already have that on the way with a bigger spinny thingy that does the ‘hint hint….’ more airflow part.
