- companies are now producing resistor plugs..beware however these are often not true resistors...they have a small coil of nearly resistance-free wire, wound to act like an electronic 'choke'...or, inductance device...electronic ignitions may NOT like it and could lead to problems...this has previously done with spiral-wrapped ignition wire....sold as Suppression Wire
- when using resistor plugs and non-resistor caps, there is a danger that you might install non-resistor plugs later on, and injure your electronic ignition
- better to use the resistor caps as normal, the proper resistance will increase the length of time the spark lasts, allowing better igniting of the fuel-air mixture
- some types of RFI interfere with electronic ignitions and other electronic devices...the resistance in the plug caps have several functions...
reduces the erosion of the electrodes in the spark plugs
RFI.
prevents RFI being conducted into wiring and thereby getting to the Hall element in the Boyer Microdigital ignition, etc.
proper circuit resistance ensures correct spark strength, length and duration...the coil(s) and engine were designed to complement each other
