Doug G. Posted March 1, 2017 Report Share Posted March 1, 2017 It isn't mandatory, but an SI is out about a new type of plugs (two gaps instead of one) and (90 deg.) plug wires. I haven't been able to find them. Has anyone else? Curious about the cost. Link to comment Share on other sites More sharing options...

Roger Lee Posted March 2, 2017 Report Share Posted March 2, 2017 They are not out yet and neither are the prices. I will bet most people will stick with the NGK. Nothing wrong with the NGK, but they didn't want to sell to Rotax any more because they were sued once. It's strictly a political and liability issue otherwise Rotax would keep using them. Personally I see no reason to switch. The new plugs are made for Rotax, but I'm pretty sure they are just a Bosch plug. I have found them for the 912UL, but not the ULS yet.

Runtoeat Posted March 3, 2017 Report Share Posted March 3, 2017 New Rotax plugs look like a typical Champion twin electrode aviation plug. Hope they don't cost as much for those who must use these! Link to comment Share on other sites More sharing options...
