Doh,
I thought I was going to have great news for you guys. I was checking out the Weber website looking for a single side draft intake for my B210. In any case, I click on a link for "overstock and discontinued items" and right at the top is what looks like an E16 twin side draft intake. It says $50, three left. Link is here:

I sent an email asking if they were E-series intakes and got this responce:
"We have two left, we really don't know what they fit. If the photos don't
let you know we can measure if you want."
Pierce Manifolds Inc.
So I got out an E16 intake and looked at the bolt pattern. Close but no cigar. It looks like an L-series intake to me. What do you guys think?
