What is the internal diameter and length of the air hose from plenum to air filter box (barrel with a trumpet on the bulkhead)? The only one we can find is NAS, costs a fortune and as rare as...on my last V8 I had a length of corrugated hose but can't recall the dimensions.
Any suggestions for a replacement tube/hose?
One of the last missing bits for my V8 conversion.
Cheers.

If you've got plenum and airbox can't you just measure the diameter and if fitted the length required?...

Can't help with the dimensions, but flapper or hotwire?
The convoluted hose goes from the plenum side of the air flow meter to the plenum on both.
Hotwire: http://new.lrcat.com/#!/1230/76077/76078/6052
Flapper: http://new.lrcat.com/#!/1230/76077/76078/6053
The flapper has a separate rubber hose from air cleaner to air flow meter & IIRC that hose has ends of different diameters.

Can't measure as it's 40 miles away but I'll phone and check.......

Found it, 73mm at plenum...80mm at AFM and about 800mm long.

The one above for a hotwire (which mine is) isn't long enough as this type the airbox isn't on the bulkhead.
No matter I know the dimensions now and will find some appropriate hose.
