- Original Factory Era Look. Original 1983–1989 factory lines left Stuttgart in yellow zinc, before Cohline transitioned aftermarket/OES production to RoHS-compliant silver zinc plating. If you are doing a concours restoration, you'll want to match the original yellow zinc appearance shown here. The crimps are stamped "made in W. Germany" which dates production before Oct 1990.
- Porsche 911 Carrera 3.2L (1984–1989). Fits Coupe, Targa, Cabriolet, and 1989 Speedster models.
- Porsche 911 Turbo / 930 3.3L (1983–1989). Fits Turbo models equipped with factory hydraulic chain tensioners.
- Earlier Porsche 911 & 911 SC (1968–1983, Retrofit Only). Fits earlier air-cooled 911 models only if upgraded to the Carrera hydraulic pressure-fed timing chain tensioner kit.
What It Does & Finish Notes
- Pressurized Oil Feed. Routes pressurized engine oil from the rear engine oil line fitting to the right-hand (passenger's side) camshaft carrier, which in turn feeds the right hydraulic timing chain tensioner.
- Supersession & Compatibility Note. Porsche superseded
93010734807 through 93010734811 and 93010734812 to 93010734817. When switching to the updated 93010734817 rubber/metal line, Porsche specifies pairing it with the updated right-side tensioner hardline (93010734818).
