Spark Plugs RIMFIRE Vs. RCExcel.
Dear all.

I Would like to know if the 1/4 32 RimFire spark plug is so superior to the RCExcel spark plug.

I can buy RCExcel from himodel.com for US$10.32 plus US$4.85 shipping costs.
The RimFire costs US$19.00 plus US$ 8.40 shipping cost.

So, my question, is it so superior that justify the double price?

I'll use it on a Saito 180 4st converted to Ethanol with stock carb on it.

After converted, When using Ethanol or gasoline, the engine shakes a lot and I cant get a reliable transition, but when using the 4st cool power fuel, it works as a swiss watch...

Any Ideas?
