Yup. The well in them is very shallow and even if it fills with deposits they can't short the gaps. It also gets the spark farther out in the mix and the performance seems a bit better. I put them in all the flight school engines that were approved for them. All engines went to TBO with no issues.Thanks, Dan.
Am I correct in my thinking that the electrodes are in a hotter area and that, plus the more open area around the electrodes, make then less susceptible to fouling?
Champion makes a different nut for their sparkplug gapper for these. It has more threads to allow the plug to sit farther back so the screw can push on the ground electrodes properly.
Get the Tempests so they don't sell you old-stock Champions with the old resistor setup.
Check the chart. Not all IO-360s are approved for them.
