Ngk.... How many k on it and are the plugs fouling?

NGK has always been my go to plug in anything I run

NGK all the way. We have done some comparisons on plugs in various machines and found no significant different in power, fouling or fuel/oil consumption. Even within the NGK plugs, I tried a high priced Irridium tipped with no noticable difference but lighten the wallet. I am still running the irridiums in all my sleds but would run any of the NGKs of the right flavor and heat range. Just make sure to run a resistor plug if thats called for or problems.

my machine only has 1200 km on it and i put a new ngk in it the other day and i went to check it today and its already fouled so im thinking my engine is in need to servicing
