Hi,
I have a question about spark plug.
OEM spark plug for my carb. 3F is Nippon Denso W14EX-U. It's non-resistor type, I heard.
But OEM plug for US 2F motor is W14EX-RU.
The letter R means resistor.
I'd compared those two type of plugs before (W14EX-U, W14EX-RU) but I couldn't catch any dfference when driving.
What are differences between resistor type with non-resistor type ?
Thank you,
Oh, Min Seok
