RX-3 Spark Plug

Did a quick search and nothing turned up, looking for a Stock Spark plug number and a NGK Number for the RX-3

I thought I had seen it posted before but couldn't find it.

TIA

The RX3 is delivered with a Denso U22ESR-N spark plug. I believe the equivalent NGK spark plug is CR7E.

http://www.ngk.com.au/frequently-ask...umbers-signify

The NGK CR7E is sold as part #4578 when sold in a paper box.

The NGK CR7E is sold as part #1482 when sold in a plastic blister pack.

I added a link to this thread in the RX3 Tech Sticky, under the 'Maintenance' subheading. The RX3 Tech Sticky is permanently pinned to the top of this forum.

Has anyone tried an Iridium plug? Any benefit to it over the standard?

i have an iridium plug on my RX3. Other than peace of mind (using a known sparkplug with efficient arcing), no noticeable benefit.

Are you running an NGK and if so, what #? I like iridium plugs, if not just for the longevity. Have them in everything BUT the RX3.

If I had a RX3 it would get either a Denso (IU22 / 5361) or NGK (CR7EIX / 7385) Iridium plug the second after I uncrate it

I only went by info I found on this thread... let me know if the spark plug is a different number on your bike, I can help find an Iridium replacement if the plug is different than posted on this thread

I am indeed running the NGK Iridium CR7EIX that Azhule quoted. Unlike the old Vino 125 I had where the Iridium spark plug made a noticeable difference, the RX3 doesn't really feel any different. But knowing the quality of the spark plug and hotter spark is worth the price of the plug if nothing else IMO.
