Until someone does that, that will remain speculative. Obviously though, the backlit louver pics I've posted with my c&ps show far more than some light. I'll continue to try to include a pic with light down tube as ultimate proof of louver openings. I've found especially with smaller applications like 6607/14612, and 7317/14610 with smaller outlet opening it provides the best perspective of all louvers with no concern for camera angle. Since I now have a stash of Puro made Bosch Prem 3323, and at least one member regularly posts that manufacturer as having suspect louvers, seems best practice for me. Speaking of Puro louvered tubes, below is a pic of a PL14612 made in 2018 I posted 6/19....... I have a feeling that even very closed up louvers will shine some light through them when a light is put behind them.....
I wonder if wire wouldn't rub through the filter material if left on long enough?I posted (year+ ago maybe) of an exploded view of a filter that showed a metal wire center tube, like an eCore, but metal. Can't recall what brand it was.
Looks like smooth round wire, see post 36. Not sure if ACDelco actually uses this design, or it was just a concept.I wonder if wire wouldn't rub through the filter material if left on long enough?
