new cool air intake

I spent half an hour making and installing a new carburettor air intake. The stock ones take warm less dense air in and so I thought it would run more efficiently with cooler more dense air from down near the road.I used big bore corrugated plastic pipe from E-Bay. I fastened it on with a self tapper after cutting two or three inches off the air intake. It is pretty clear in the photo. It works well and was simple.
