Complete Vacuum Advance Distributor like the original style ones fitted by VW. This one comes complete with the 12 Volt electronic ignition module fitted so is a great upgrade. 034 advance curve with centrifugal and vacuum advance. Comes as pictured with the red cap and ready to bolt in and go. Fits the Beetle Split Bay Ghia etc with the 1200-1600 engine and 12v electrics. Requires a Bosch Blue or other hi-energy epoxy filled coil (3.4 ohms primary/12k ohms secondary) with built-in resistor. An external ballast resistor may be used between power source and distributor if your coil does not feature a built-in resistor.
