OEM Plus Airbox / Air Cleaner Assembly for Porsche 944 Turbo and Turbo S (1986 to 1991)

The Air Cleaner Your 944 Turbo Should Have Left the Factory With

Pop the hood on a 951 and the airbox is the first thing you see. Decades later, most factory boxes look every bit their age. This is the one you leave the hood open for.

Our OEM Plus airbox keeps the factory shape and every factory mounting point, then upgrades everything else. Updated geometry inside for better flow. SLS printed PA12 nylon with a shot peened finish. A clear cast acrylic lid that puts your filter on display. Brass threaded inserts and stainless hardware throughout. It looks like it was always supposed to be there, and it bolts right in.

$1,600. The first batch is in stock and ships in 1 to 2 business days. When it's gone, every box is printed to order with about a 5 week wait.

Why It's the One to Buy

• The cleanest look in a 951 engine bay. No cone filter, no loud colors, no bolted on mess. It reads factory until someone looks closer and sees what it really is.
• Your filter, on display. The clear cast acrylic lid shows off the filter and makes checking it easy.
• Better flow, same footprint. The outside stays very close to the factory box. The inside gets updated geometry for better flow.
• Built to be serviced for years. Brass threaded inserts so the threads hold up to every filter change, and stainless hardware that won't rust.
• A finish that looks like a finished part. SLS printed PA12 nylon, shot peened for an even, clean surface.
• Sealed at the fender. A TPU grommet seals the tube where it meets the fender.
• Made in the USA. Designed by Brockett Built in central Illinois and printed by our US printing partner.
