Hey everyone, I just want to add I finally dropped the plow and went ridin yesterday and it was beautiful out and had a blast! But on another note, I was wondering if anyone runs a different Brand spark plug in your quad. I personally dont like NGK plugs. I have had nothing but problems with them and I have already replaced mine with a stock number 3923 Autolite. Haha yes a direct interchange from the BKR6ES NGK. I know in the manuals it says if you run any plug other than the BKR6ES it can cause serious damage. But honestly my quad is running awesome and actually seems to run better! I'm not a big fan of Champions either which the stock number of the Champion is a 71 aka RC12YC. What's anyone and everyone's input on your preference of spark plugs??? Have a nice day!
