The 440 ( Fan ) has a bunch of different plugs that came with it. Some BR8's and a few Br9's. I have a Bunch of new leftover BR9ES's. Can I use them?

Gotcha. Ill pick up some 8's them when at the shows. Rather use corect plug then be chap and stuck.

I use nothing buy Ngk BR9ES Plugs in my 97 Mxz 440 Fan.

BR9ES should be fine in the fan cooleds. They seem to run on the lean side anyway. 8 may cause problems. I would try the 9's first and look at the color after you run them a few miles. I believe it's speced with 9's from the factory?

My brother has a '98 MXZ 440 fan and i believe he uses BR9ES and thats what came with it when he bought it new. I am going to be using the same plug for my '99 MXZ 600, as thats what came with it as well, if its the wrong plug for my 600, by all means, email me @ [email protected] and let me know what i should be running, Thanx, Jim

Looked up NGK, and they show the BR9es, so Ill pull the old ones, and go to 9's , and check them for the golden color once we get some snow, or a Heavy Frost LOL.

Run BR9EYA's.

Great plugs, have not fouled one yet.
