I just bought my first Purolator Boss PBL24011 filters and the louvers look super sloppy and not fully open. I paid about $15 each and I'm worried to use them on my 1996 Caprice and 1997 GMC Sierra. These were the best pictures I could get but you can see the louvers were not cut well and are odd shaped and jagged looking and nowhere fully open. I was expecting a much better looking filter. My Mobil 1 filters look waaaaaaaay better and Mann-Hummel makes them both? What gives? Should I return these?
