OE Match
This replacement knob fits onto the heating control lever in classic Porsche 911 models (1978–1989). It restores the correct factory-style look and tactile feel of the original cabin control.

Porsche 911 1978 - 1989
Diagram ref no 33
This OE-match heater control lever knob is the small but essential trim piece that finishes the heating control lever assembly on the Porsche 911 (1978–1989). Made to replicate original dimensions, profile, and fit, it installs directly onto the lever to provide a clean, factory-correct appearance. It’s ideal for replacing worn, cracked, or missing knobs and is a smart upgrade during interior refreshes and restorations.
This knob provides a secure, comfortable grip for operating the heating control lever. It improves day-to-day usability by giving you better control when adjusting cabin heat, while also restoring the finished look of the interior control panel area.
The heating control lever knob acts as the user contact point on the heater lever, helping you move the lever smoothly without slipping. It also protects the lever end from wear and prevents sharp edges or exposed hardware from detracting from the interior appearance.
Over time, interior plastics can fade, become brittle, crack, or loosen from repeated use and UV exposure. A damaged or missing knob makes the lever uncomfortable to operate and leaves the interior looking incomplete. Replacing it with an OE-match knob restores proper feel, improves usability, and helps maintain a factory-correct cabin finish.
When to Replace:
• Knob is cracked, broken, or missing
• Knob feels loose on the lever or slips during use
• Surface is worn, smooth, or uncomfortable to grip
• Interior restoration or refresh is being carried out
• Heater lever end is exposed or looks unfinished
