Those who just purchased the Bosch 3401, what does it look like on the open side? I opened the last two boxes on AutoZone's shelf and one had a black plastic valve and 4 holes on the metal around the thread. It looks like it has a spring below the threaded part to hold the paper element in place. The other one had a red plastic valve with about a dozen smaller holes. It didn't have a spring inside. Both were black on the outside and had the 3401 sticker on them. One had a little dent so I only bought one.

Does Bosch has multiple suppliers? Why would be the construction be so different on two filters probably from the same batch of shipment? I think the important part is the filter element shape, size and they both equally capable. Just thougth it was strange...
