For those of you who might have been following my oil pump priming process, a short update before my question(s). I used my DIY pressure luber to force oil thru the engine's oil lines and then cranked the engine using the starter while the coils and fuel injectors were disconnected and oil came thru the turbo oil feed line. I then waited 4 days and tried again and then tried again today. Each time, oil started flowing during the 4th starter crank cycle, so I'm happy there is oil flowing thru the motor.
Now my questions - In an old spark plug thread over on TDS, Funinthesun posted an NGK engineer had recommended using an NGK 92182 Iridium plug, pre-gapped to .036. Since I prefer the longer life of iridium spark plugs, I ordered some NGK 92182 plugs thru Oreilly. Hahn recommends their standard NGK 4306 plugs. When I went to swap the plugs, I found that Iridium plugs (AC Delco 41-103/12625058) were already installed, presumably by my dealer during a service, or else Polaris actually shipped my Slingshot that way. Since Hahn says the original plugs can be regapped to .030 and reinstalled, I regapped the AC Delco plugs to the .036 used by the NGK 92182 plugs and reinstalled them since the AC Delco plugs looked pretty clean.
Anybody tried using either the AC Delco Iridium plugs or the NGK 92182 Iridium plugs? The NGK 5306 V-Power copper plugs?
Just thought I'd ask before going out to finish wiring the SCG-1 Bost/AFR gauge and then test-starting the engine.
