Going on third vehicle with same filter. Originally a Isuzu Rodeo and after 175k miles engine blew a head gasket, replaced it with a Isuzu pickup from my with and put another 120k on it. Tranny started slipping and it wasn't 4x4 so got a Blazer. Have almost 250k on Blazer. I might make that million miles. Keep a cleaning kit in truck when I have oil changed so they can clean filter. All is well and gonnna stick with them.

This is an interim replacement until I get the cold air system in. Gotta be better than the other openings for replacement filter elements, for sure!
