Hi, I came across this performance mod whilst clearing aspace in the garage, its a venturi which was sold in Beetling & Safer Motoring to increase the flow thru the Type 1 Manifold. I cannot remember the company or their slogan .
Dimensions the mod reduced the size to 26mm
the gaskets are std 32mm
The 1st photo is the top view the 2nd shows the underside
Do you remember these?
