I'm thinking of getting new plugs for my bike. I know the manual asks for NGK CR8EK plugs, but after a quick check with my local dealer, they are $15 a piece!
The CR8E is 1/3 the cost, at $5 each. I saw both plugs, and the CR8E seems to be a standard plug, whereas the EK version has two electrodes.
If i recall correctly, the last time I took out my plugs for inspection, they were normal, single electrode plugs.
So do I have to opt for the EK versions? Or should I just stick with the E?
