Has anyone heard of replacing the Vanagon waterboxer Water-to-oil
oil-cooler with one from a Mazda 12A rotary engine?
The 12A rotary engines used oil coolers similar in design to the stock
VW one that your oilfilter screws onto.

Seems I saw somewhere that the Maza water-to-oil unit performed better
than the VW one.

Is there a particular reason that people look for the Mazda air-to-oil
units for the Westys?
Is there something inherently better about them than any other oil cooler?
