The fear is that they might not be opened up enough, and we've seen some examples from Purolator posted here where they weren't even punched through but just 'bumps' on the center tube.
So, the louvered center tube design leads can lead to possible manufacturing problems, and they need to be inspected before buying the filter to ensure they are opened up well - regardless of the brand of fitler.
Like I said, purolators poor quality is what's causing the fear. If purolators wouldn't be having quality issues ( tears, closed Louvers) like they have the past 2 years, everyone would be drinking the louver koolaid. When done properly Louvers are an efficient design that creates less waste in the manufacturing process.
Yes, obviously there can be a manufacturing quality issue as seen posted here in the past. So it's best to inspect them before buying. IMO, there nothing wrong with doing that knowing there could be manufacturing QA issues involved with louver forming during manufacturing.
Most here know that there is nothing wrong with the louver concept and design, IF they are made correctly.
