That's what we found on our Purolators for a FZ-09.
I posted the pic to their Facebook and here is the response.
So it was a design change so no more using them on bikes. {113}
From Purolator.....
"Purolator Congratulations - you are our first Facebook follower to identify this important design change! In appreciation, we would like to send you some Purolator goodies.
At Purolator, we continually strive to provide improved innovation and performance of our products. Late last year we re-designed the baseplate assembly for our 14612 product offerings. This change included PureONE and Purolator Classic as well as our commercial brands.
Why the change? The 14612 series fits many applications from families including Chevy, Ford, Mazda, Infinity, Subaru and Nissan. A few of these applications are particularly difficult to reach. In order to improve the overall customer experience, we changed the baseplate design to provide additional thread engagement and a more noticeably “snug” feel when hand-tightening the filter. This improvement was accomplished by: 1. Changing the base plate from a concave to a convex design (as it shows in your photo); and 2. Slightly increasing the height of the gasket.
While the “feel” of hand installation is noticeably enhanced with these changes, it is always recommended to use a torque wrench specification of 12-15 Nm (approximately a ¾ final tightening turn) to ensure proper seal.
