Product details
The IWIS endless timing chain drives the camshaft timing arrangement in the specified air-cooled Porsche six-cylinder engines. This is the closed-chain version supplied without a master link, so it should be selected to suit the engine assembly method. A connecting-link chain is a different product.
Technical Details
- Manufacturer: IWIS
- Manufacturer part number: 50031696
- Chain type: endless/closed, without master link
- Cross-reference: 99310552900; related references include 90110552900 and 91110552900.
- The engine uses separate left and right chains; check the quantity required for the work being performed.
Fitment & Compatibility
Match the chain reference and installation method to your 911, 930, 964, 993 or six-cylinder 914 engine. This camshaft chain is for the corresponding flat-six arrangement; it is not a timing-chain conversion for the four-cylinder 912 or 914-4. Confirm engine identity on rebuilt or swapped cars.
For over 20 years, PMB Performance has helped Porsche owners work through engine and model changes. Send your engine number if you need a chain-reference check before assembly.
