Turbo_Boss Posted November 20, 2008 Share Posted November 20, 2008 Hello Guys, I have been using the regular NGK plug in my 582 (Top Mounted) since I have it but I want to try Denso Iridium Spark Plugs. Questions: What Part Number I need to use for my Rotax 582 (Not Blue Head and my engine is Top Munted) Do I need to calibrated them? Or use them as is from the box? What advantage I will have using these Iridium plugs VS the regular NGK??..........BTW, I change them every 50 Hours Is there is a chance I will see better o worst EGT, CHT o Water temperatures on my EIS using these plugs Or things will be the same as using the regular NGK Plugs Any other advice??
