Spark Plug - 02 XCSP? - Snowmobile Forum: Your #1 Snowmobile Forum

This sled came with NGK br9es plugs in it. I checked the NGK site and they list bpr9es as the correct plug, which I think is just a platinum plug. Am I ok to continue running the br's or do I need to change for some reason to the bpr's?

That's the difference between them.

The two plugs will perform equally when new, but the platinum plug will last longer.

Polaris specs a Champion RN57YCC plug with .025" gap. The BPR9ES is a bit longer electrode than the BR9ES and is an acceptable substitute to the Champion plug. The P stands for Projecting. Your sled's combustion chamber is designed for the P plug, and that is what you should use.

The premium platinum plug would be a BPR9EP part number with the second P indicating the platinum

I liked the Champions for my Edge. All I ever ran

Thanks guys! I was hoping not to add a third plug to the tool box. The other 2 sleds are on different NGK plugs already. Oh we'll!

I just bought new NGK plugs for my RMK, which calls for Champion RN57YC. The Champion RN57YC / NGK BR9ES's are for the non-VES Libertys, (mine) the longer Champion RN57YCC / NGK BPR9ES's are for the VES motors. (yours)
