I03 BILLET HEATER KNOBS

Rennline’s billet aluminum heater control knobs are the perfect inexpensive interior upgrade for any Porsche equipped with this feature. Factory heater control knobs become faded, cracked, and/or unsightly after years of exposure to UV light. Rennline billet knobs are machined from 6061 aluminum and are available in red, silver or black anodized finishes for a durable, long lasting appearance. Simply tap off your old knob, and tap ours on, installation is literally a snap.

Three Colors
