I was curious about converting a Dauntless V6 oil bath air cleaner to paper element just for simplicity and cleanliness, but didn't want to modify my original oil bath air cleaner as it was in pretty nice shape. Did some searches, but mostly found threads on the 4 cyl oil bath conversions. I found a rusty one for $30, so...why not? Worthy of note: This only requires modification to the center section of the oil bath air cleaner. Edit - After additional research and some good feedback from Maury, WIX 46023 is the best fit for size and CFM ($12 at local parts store). The center section is too tall and needs to be shortened... Removed the rolled rim holding the bottom flanged plate on by carefully grinding it away... Measured, marked and cut the center section down to size (thin cut-off wheel in a small angle grinder worked best) Drilled some small holes in the flange plate and re-attached it to the shortened center section with small plug welds. I suppose you could leave some small tabs on the center section when you cut it off, make some slots or holes in the flange plate to align with them, then bend the tabs over if you don't have a welder. I ended up with a very tight seam where the flange plate met the center section after spot welding, but ran a thin bead of gasket maker around it for good measure and an air-tight seal. The filter is a snug fit inside the top flange (had to work it in there a bit), the bottom also fits nice and snug in the lower housing. End result after bead blasting, primer/paint.
