That’s the reason hand tight due to the heat cycles, tightening it upThe point is, a little overtightening coupled with mny heat cycles tends to render these composite filter housings troublesome.
No one is saying you or I don't know how to install them. I am saying it happens all to often.
I have personally worked on 2 Carollas with filters I was afraid I was about to beak. And I think I have only serviced 4 vehicles with the composite filter.
