Bell mouth -OEM QUALITY - 28-35mm (l= 60mm)

BGM Intake funnel with 28-35 mm inner diameter.
Intake funnel which can be either completely open or driven with the air filter insert supplied. The design of the space in front of the carburettor has a considerable influence on the realised performance.
If the air filter swallows important horsepower in favour of a durable engine, the engine can only deliver its full performance without an air filter.* Because it can breathe freely. The achievement can be still further increased with intake funnels, since they optimize the flow of the air before the carburetor. With this improved flow, intake funnels have a significant influence on the performance of an engine. This is why you see the intake funnels more and more often at Quartermile Acceleration Races.
To achieve a perfect sealing effect between carburettor and intake funnel, a thin rubber strip may have to be inserted as an adapter. Otherwise CAPITAL ENGINE DAMAGE may occur.
