Sorry correct p/n is B085046 for the Donaldson. As stated above the normal 6637 will work fine in the rain so it really comes down to personal preference and how much money you want to spend. I believe the only difference is the marine version has some antimicrobial stuff made in the filter media to prevent mold growth from staying wet all the time.

 

Ordered from Riffraff. Looking forward to installing it.. now I just need to figure out my oil issue...

 

You will be happy riffraff kit works well

 

Supposed to be here today.. pretty excited.
