Project 718 Cayman T: Part 8 – BMC Air Filter

Here is another large chunk of foam hiding behind the panel next to the seat. I have to admit, the Cayman is very quiet inside during cruising. The S2000 didn’t have any of these foam bits inside the cabin, but it was a convertible and it was going to be relatively loud regardless.

While I was digging around, I figured I would go ahead and remove the Soundaktor attached to the bulkhead behind the seats. Weight reduction! Two observations: that’s a really nice bracing system going across the car and that’s a whole lot of foam on the backside of the carpet panel.

One of the bulkhead panel fasteners is actually inside the Soundaktor.

The Soundaktor is like a mini ported subwoofer. Off to the scrap pile it goes.

Hey, for whatever reason, Porsche actually put an access panel on this bulkhead panel behind the seats. It looks to be roughly in the area of the water pump. Too bad they couldn’t be bothered to put an access panel in the undertray of the car to make oil changes easier.


    1. I’ve heard with practice, it can be done in 45 minutes. If done by the dealership, the question is how careful are they and how many little black cones will they lose. Also, getting the lid back on properly seated and sealed takes a bit of work. I didn’t have it seated correctly the first time.

  1. There is a big intake restriction after the intake filter, just before the turbo. There’s a company “Ragdoll Motorsports” that has replacement turbo inlet that showed great results on the 2.5.

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