PWK-type carburetor funnel d=48mm Polini

In dragsters and high-speed racing, intake funnels are used instead of air filters.
Not only do they look very striking, but they also allow for a better airflow than air filters. From Polini, we have a version made with CNC machines.
The carburetor is not included in the delivery.

Available with a connection width of 37.5mm (Arreche carburetors 17.5 to 24mm, Dellorto PHVA-PHBG 12mm PHVA-PHBG 17.5mm),
50.5mm (Keihin, PWK, Oko),
55.5mm (Koso)
and 44mm (Mikuni).

If you are not sure about your carburetor, measure the diameter of the air filter connection.
