30 mm long FULL-RADIUS bolt-on trumpet for 45 and 48mm carburetors FR45-30

Top quality, machined from a solid billet of alloy.
These trumpets measure 30 mm in total length.
These trumpets are of the so-called Full Radius type which are specifically designed to draw in more air than the regular shape trumpets.
The "full radius" edges create a greater "funnel effect" and are therefore more efficient.
Please bear in mind that your regular air filters might not fit anymore and that, for optimum effect, you will need to keep at least 25 mm clearance around the mouth the of the trumpet.
Diameter at the flared end is some 79 mm.
They feature 65 mm stud centers and will fit, amongst others, the following carburetors:
Please note that these trumpets do NOT fit the vertical Dellorto DRLA and Weber IDF carburetors!
