Rennline's billet aluminum teardrop defrost knobs are the perfect inexpensive interior upgrade for any Porsche equipped with this feature. Factory 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 unscrew your old knob, and screw Rennline's on.

Compatible with 911/912/930 ('65-'89) or any car with a threaded lever.
