Porsche 911SC Ignition Distributor Vacuum Unit

Very precisely CNC machined from billet aluminum with a flourosilicone diaphragm and all stainless steel hardware. Manufactured and individually tested to a much tighter tolerance band than original equipment published specifications. Each unit includes a certificate of test showing its’ individual vacuum/advance response plotted over an expanded-scale factory vacuum advance curve. Unlike the original “tin can”, this unit is fully serviceable (and much prettier too!) Stainless steel mounting hardware included. Please allow 3 days for us to ship.

Warranty: 60 Months
