I think the briggs 492932S will cross with the Kaw filter.
Yes it dose said that back in post # 21
Even put the links to the Stens & Rotary catalogue pages.
AFAIK Both of them are USA made Champions Oregon & Prime Line will also do a substitute filter but no idea where theirs are made.
At least one will come out of China as the Briggs short filer is available from a dozen or more factories in China
As for the price , read post # 25.
The volume going through Kawasaki dealers would be lucky to be 1/10 of what passes through any one of the after market suppliers.
The cost of raising an invoice at the last warehouse I ran was $ 2.75 and the price of a hand pick was $ 3.25 which rose to $ 4,95 if they were so high it became a fork pick.
Places that invoice directly from a web page the invoicing price goes down to around 15¢
Then the parts sales team have to eat and have a cost / hr regardless of weather they are filling orders or not.
Unless the dealer has a direct reorder system which reorders parts as they are sold you then need a storeman & some one to place an order
As for the parts substitution it will be simply something like the previous filter will not fit on one of the new mwers so in order to keep costs to a minimum Kawasaki have decided to use the newest filter on all models.
This is sound proceedure as it increases the unit volume through put thus lowers the price and of course reduces the inventory needed to be kept at the warehouse and at the dealers.
As posted way back, the specks on all mower oil filters are so close you can just about substitute any of them for any other one of them
When they speck 28 micron that really is 25 to 30 micron and in many cases the same mesh size is labled differently from different suppliers.
All mower oil filters are way over capacity for the job they are doing because it is cheaper to use a car sized outer case than have a unique 1" diameter x 2" long filter which is about what they need.
The 12 packs are about 2/3 the price of individual filters and the 24 packs are about 1/2.
Those discounts come from volume effiencies, one pick & one invoice for 24 items.
And it probably costs the same to truck 24 filters as it does to truck one.
I buy the Briggs long in 24 packs and all the others in 12 packs, usually during the off season when discounts are happening.
