I HATE the toilet bowl noise of the air cleaner that comes with a Weber install. I hate the hot air going into my engine. I hate the dirt I find inside the throttle even though I cleaned and oiled the filter. I concluded I needed something better and with that goal in mind, I went Junkyard shopping. please excuse the upsid edown pics and general hokey nature of the job as it's just a first attempt to prove the viability of the concept, I'll make better parts now that I know it works.

why is the photo sideways I cannot fix. but this is a can air filter for a buick 3100 from the early Nineties?. It is metal, which I can weld. the outlet nozzle is on the top and is 3 1/2 round. the inlet can be clocked in any relation to the mounting bracket underneath. I screwed it to the fender and pointed the inlet at the back of my headlight where the nice cool air comes in two inches away.

again with the crap upside down pic. I can't. I've tried, I just cant even. but here is an overview. metal duct from the Buick can filter to a dog bowl with an exhaust pipe welded to the side. A flat plate made from a scrap saw blade base. I'll probably keep the dog bowl bit, use the rubber ring from a scrap air filter to seal the base of it to a better base plate. two bolts welded to the surface of the base and two nuts and gaskets keep the lid on.
the original rubber hose will be replaced with a 2 inch long section of exhaust pipe expanded to fit the air cleaner lid. or perhaps flared from 3 to 3 1/2 and then welded to the lid. then I can throw away the ugly black hose. A brace from the can body over sideways to the inner fender seems like a good idea too.
DOES IT WORk. hell yes it works, cabin noise is really reduced, I can talk at normal volumes again. power does not seem to be affected. It will take some more sealing and work to make this actually work every day but I knocked this together in an afternoon as a test and I'm impressed with it. The Buick seems plentiful a U-Pull yards, the one I went to had three examples and because it's not got any sensors in it, all the air cans were there.
