I picked this up from the Fram Web Site: Well I understand what you say - it looks like Fram will replace an engine found defective because of their filter. Now proving that may take some effort, but at least you have some basis for a starting point.

FRAM filter products will be free from defects in material
and workmanship under normal use and service, provided

properly installed according to Honeywell Consumer
Products Group's instructions. In the event any FRAM filter
product is found by Honeywell Consumer Products Group
to be defective within the manufacturer's recommended
change intervals, Honeywell Inc. 's sole obligation under this
warranty shall be to repair any such defective article or
engine which is damaged as a direct and sole result of a
