The NGK JR9C plugs are supposed to be the hot ticket. They must be replaced about every 6 to 10 races. I use a platinum plug equivalent to the DPR8EA.

They are a Honda part number 98069-5991f or NGK DPR9EVX-9. They work extremely well for me with no complaints.

Thanks for the info, I'm also going to look into the Denso Iridium Spark Plug  IX24B.

I've been using the JR9C plugs but have been wanting to try the fine wire irridium plugs.  I used them in my 4 stroke 200cc OHV Yamaha kart engine and they worked the best when burning gasoline.  I just havn't done the homework on the number cross reference.

Sorry to revive and old thread but when you say replace every 5 races is this meetings or runs?

Thanks

Hi Dan,
 I believe meetings. I used to pull my plugs and clean and re-gap them the end of every race. It gave me a chance to see where I was at on my tune up. They were usually still good after several weekends of racing, but I replaced them anyway.

JMHO,

Steve,

Ok on a race day we run either 3 or 4 races with a couple of practices. So im going to go with every 3 meetings. Just annoyed how cheap everything is in the US!

Do you re-gap the JR9C plugs to 0.9mm the same as the DPR8EA plugs?

I'm not sure what everyone is using for spark plug gap. I'll let some of the more qualified folks give you the info on that.

The only iridium plug I can find an actual cross reference # for the JR9C is the Denso CWIX27
