Hi, can anyone quickly give the part number or information for an air filter for my 446 (Onan) engine? I sure would appreciate it, I think we have solved the 'blowing oil' problem, but they sent the tractor back to us without the filter!
The Genuine Onan Part # is 140-1216 I think the new number is C-20398. That is for the filter that's about 3" wide/tall. I assume that's the one you need.
A Kohler Air Filter will also work great.
Fits Models Onan 140-1216
4 5/8" ID x " OD x 3" HT
Please consider these over the FRAM garbage, I mean filters, and it's a good idea to use a prefilter. (especially on a Fram)
Onan# 140-1216 airfilter
Kohler# 45-083-02 airfilter
NAPA# for these filters 7-02226
NAPA # for prefilter 7-02287
