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

Denso U22ESR-N | (10mm) NGK CR7E is close to above

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

http://www.sparkplug-crossreference.com is very useful

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 :hehe:

Thanks for the info! I'll grab one in town today.....

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 :tup:

Thanks guys for the feedback. Might have to pick one up while at the parts store as well.

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.
