The Davis Diesel System is our “HDI” (Hybrid Diesel Ignition), which should not be confused with the older European system. From a Cox .020 up to a Super Tigre 6000 twin the Davis Diesel converted engine provides more bang for the buck.

Remember, two heads are better than one. This American-made invention is suitable to use for over 140 engine models from no less than 15 engine manufacturers.
