This filter came off my Jeep Cherokee 4.0 after a 4,000 mile OCI. The media looked okay, and the ADBV was still functioning well.
Something in the following picture is not right:
Yes, that is the top end cap sitting next to the filter. It fell out when I opened up the can.
More pics of the end cap:
A few notes:
This filter was only in use for 4,000 miles. The Jeep is not driven very hard at all.
While every filter has the occasional failure, of the 3 filters I have cut open in the past few months, 2 of them have had end cap failures. This filter and a Bosch D+. What is interesting to me, is that I have cut open FL-400s filters before and they looked great. Those filters were purchased at Advance Auto. Both this FL-400s and the Bosch D+ with end cap failure were purchased at WalMart. That is not to say WalMart filters are of lesser quality, but it does make me wonder, considering the ONLY filters I've opened that have failed have been from WalMart. I'd say I purchase about 40% of my filters from WalMart, 10% from Autozone, and the other 50% from Advance and Napa.
