I never really liked that the Weber carburetor's K&N filter had a lot less filter area than a stock air filter. The stock air cleaner setup also offers use of the cold-air "snorkel". While I'm not entirely sure how much efficiency and/or power the slightly colder air gives the engine, I like utilizing the stock setup. Also, even though I'll be swapping this all out for the EFI manifold in a few months, I like the aesthetics of the stock equipment, too.
So, Jay and I cut a big hole in the underside of the stock air cleaner and cut an adapter plate form a piece of
ahem found flat aluminum.
