Often the cause of poor ignition is when your High Tension Leads or HT Leads as they are more commanly known are breaking down and need replacing.
These HT leads are for use on all VW Baywindow Buses fitted with 1700cc, 1800cc or 2000cc Type 4 (pancake) engines and all early Type 25 Buses with 2000cc aircooled engines.
The distibutor cap ends on these leads are for use on the socket style distributor cap and coil as opposed to the later style which have pins on the top of the distributor cap.
HT Leads have a thick outer insulation around a central conductor core. This thick insulation prevents arcing from the cable to any earthed engine component. The central core is normally manufactured from copper.
RFI (Radio Frequency Interference) is naturally produced by the spark being radiated by the wires which may cause malfunctions in your electrical equipment.
Various manufactures have come up with various solutions to this problem by suppressing this.
In a nutshell the more electrical equipment you have in your car the better the quality of HT lead you will need.
If you are running electronic ignition then it is vital that you use a good quality set of leads so as not to effect the running of your car.
Sold as a set of 5 leads which connect all the spark plugs to the distributor and then a smaller lead which connects the distributor to the ignition coil.
