NGK CR8,9 or 10EK Plug
NGK CR8,9 or 10EK Plug
Seeing what plug everyone runs, why and what the difference is between the three.... I have heard the 8 wont foul as much as a 9 but a 9 runs hotter and is a better plug, does anyone have experience with a 10? Manual calls for a 9EK...Tks

The MX400, FX400 and X440s owners manuals, 2001 print, say 8. The 2002 and 2003 Engine parts catalogs say 9, but then indicate the same Wiseco piston, while the 2002 ATV Owners manuals says 10?... The 2003 Bike Manual says 9.
sheesh!
And I wonder, has anyone ever seen a number 10 plug come out of a factory Cannondale?
