Good point ... not sure that I was aware of it until I saw
the bits in the Moss Mag.

The 'A' already has the 'snout' ... there is an 'air duct'
(metal tube) that penetrates the radiator support on both
sides ... on both sides a hose runs from the grille area to
the front side of the radiator support ... on the right hand side
a hose runs from the rear of the radiator support to the heater.
IOW, the 'A' does have a 'cold air hose' for the carbies, but it
stops at the radiator support.  My thought was to attach a
hose to the rear of the radiator support (the flange is already
there) and extend it to a 'cold air box' fitted to the carbies.

Do you think the additonal hose and 'cold air box' will provide a
measurable improvement in performance? ... or is the existing
'cold air hose' adequate?

Safety Fast! ...
