I think this one needed a change :)

This of course shows the new filter still in the bag and the old dirty filter.

Notice the broken lockdown spot on the breather box. Seems to be a common problem on trucks like mine. I will be ordering the AIS Severe Duty airbox

to replace this one.

Another view of the broken tab. The bottom of the airbox is suposed to have a spot there to allow the clip to tuck under.
