Reviews

When my Dynon oil temperature sender failed (temperature indications fluctuated wildly, WAY into the red), Dynon blamed my engine ground. I couldnt find anything wrong there, so I replaced the oil sender with this two-wire unit. Problem solved -- My oil temperature needle is now rock steady, and apparently accurate.
