Pertronix Ignitor - Electronic Ignition
A solid-state electronic system... "never change points again!". Test results show the Ignitor delivers twice the voltage to the spark plugs, increasing horsepower, fuel economy and plug life. A 2:1 improvement over point type systems in current fall time for increased coil output.
Rotating cobalt magnets, mounted on the distributor shaft, trigger an electronic switching module (Hall effect integrated circuit), no points to burn, pit and corrode, no moving and rubbing parts to wear out.
Fits entirely inside the distributor, no "black box" to clutter your engine compartment. Stable timing... no need for any adjustments.
California Resources Board E.O. #D-57-2, legal in all 50 states and Canada.
Please Note: You'll need to select the correct model for your Jensen Healey- your car will have the 25D distributor or the 45D distributor. From what I've seen, most all 4 speed cars have the 25D distributor, while some (not all) JH's '75 and on have the later 45D distributor. You should check to be sure- electronic components are not returnable. The model stamp for the distributor is located on the top (looking down at the cap), inline with the vacuum capsule (opposite end of the fine knurled adjuster).
