Spectre's polished cast aluminum low profile plenum has a 4 inch inlet. It is 2.4 inches tall between the carburetor and the bottom of the hood which makes it great for low clearance applications. It measures 9.25 inches from the air cleaner stud to the inlet and 7.25 inches across the plenum at the air cleaner stud. This plenum fits carburetors and TBI throttle bodies with a 5-1/8 inch inlet. The 4 inch single inlet is designed to match up to all Spectre 4 inch tubing, filters and accessories. Use with Spectre 4208 air cleaner nut (sold seperately).

Ordered very specific parts unique to my vehicle. The team were highly engaged to ensure I would recieve the correct high performance parts for my 2018 Porsche Macan Turbo. Including requesting photos and measurements to verify fit. Very happy to order here for any part. They know their cars and their suppliers very very well.
