Best Sparkplugs For The Yamaha R6

This is a simple question. The best spark plugs for the Yamaha R6 is the NGK CR10EK Spark Plug. Here is why according to

“One reason the CR9EK’s or CR10EK’s make more power is because they take up more space in the combustion chamber, which increases the compression ratio. The second reason is that the spark is .040” / 1mm deeper into the combustion chamber. I think that increases the burning efficiency at high speeds.

They work so well that Yamaha uses installs them in the R6 from the factory.”

A great oil filter to use is the Mobil 1 M1-108 for 2006+ R6s and Mobil 1 M1-110 for the R6s models.

Expert Village also has some semi informative videos on changing the spark plugs on a 2006+ Yamaha R6. I’m going to use them until I can write my own complete guide. If you want to write one I would LOVE IT!

What have your experiences been with spark plugs?
