Uses a (or resistance wire) in the "run" circuit Distributor Cap Often uses the smaller, original-style cap Uses a large cap and rotor adapter to prevent spark arcing Spark Plug Gap Massive factory gaps (up to 0.070" ) Smaller standard gaps compared to DS1 Practical Considerations Difference with Durspark I and Duraspark II?
Ford's and Duraspark II systems differ primarily in their electrical performance and availability. While Duraspark II (DS2) is the more common "standard" system, Duraspark I (DS1) is often cited as the most powerful factory ignition Ford produced for carbureted engines . Key Technical Differences Duraspark I (DS1) Duraspark II (DS2) Primary Region California-only (emissions compliance) 49-state (standard version) Grommet Color Red plastic insert at the wire leads Blue (most common), though other colors exist Dwell Control ford-duraspark-1-vs-duraspark-2
: Simpler design with less consistent high-RPM performance Resistor Wire No resistor wire; runs on full battery voltage Uses a (or resistance wire) in the "run"
: Varies with RPM to ensure full coil saturation Key Technical Differences Duraspark I (DS1) Duraspark II
