Yes, that is exactly right. Looks like the new OE cap is made better and I'm going to switch it in the next couple of days. I think the Hengst and Mann filters just have the paper end seals ?? Our local dealer is a dick so it's nice that I now can order OE on line from Canada!
I ordered an OE gas cap as well and it's MUCH better than any of the after market ones that I tried for just a few dollars more.
