Can you Use a 2002 WR426F Steel Filter that you can clean. I heard it was something that could happen but kinda wanted to " ask the people" :)

i thought the 426 filter was a little longer. not much, only about .030. ask your dealer to show you both. set them on the counter side by side. i tried the 426 in my '03 450 and the cover didn't want to go on without mashing the filter. that is not to say i didn't do something wrong. it'd be nice to be able to wash it out.

Caution, the 450 is different length. I think the 400/426 ones are taller. And if you try a 450 filter in a 426, you will have an internal leak and unfiltered oil running through the engine, visa versa, too tall. I have screen types, dont remember brand, but its in a blue box, beleive its Emgo, and I have 4 other ones on hand in green boxes, I havent even opened those up to see if its paper or screen
