The Value Mazda filter has louvers and a coil spring, wonder who makes that. The Thai filter looks as though they want flow directly to the pleats as much as possible. The holes seem too large and the base plate metal not enough. I would say that base plate would be be weak and prone to flex. Hard to tell how thick it is.
Looks plenty thick to me. I have not heard of any failures.
It's hard to see in the pictures but there is a layer of clear resin or something similar on top of the pleats. That layer seems to go right up to the underneath of the baseplate.
The filter is very sturdy. I'm thinking the overall construction adds to rigidity rather than having a really thick baseplate with a beer can like shell attached.
