For Bosch® ignition distributors 0.237.304.016 and 0.237.303.003
(These distributors are for Porsche® 911SC and turbo 3.3L models.)

Note: these parts require skill and experience along with a distributor dyno to correctly set up the distributor advance curve.  An improperly set up distributor can destroy your engine.  If you are not comfortable installing these parts, we have restoration services for these distributors on our website, or you can bring your car to a qualified mechanic with the experience and equipment to work on these systems.
