I have been into Aircooled VW flat four engines for over 27years and I have to say when I came across this website and article about a little known or used factory piece of tin to help cool the Aircooled engine we know and love. I was shocked!
I have NEVER seen an single engine with this piece on it no matter what it was? Not on a core engine, one I pulled out of a car and tore down. Or one that I built up? And no one I talk to has ever seen or heard of one?
Why is this piece so unknown?
But it seems very necessary when you read this article. I have bought this piece and must say that after test fitting it on my cooler and fan shroud it seems completely true and needed to get the full benefit of the factory cooling system.
