Details

Polini Intake Kit "Big Valve" 17.5 / 21mm MBK Booster / Stunt, HQ 4-petal racing valve for engines with original 2-petal valve.

This reed valve has a large cross section allowing for increased flow area for the fuel-air-mixture. As a result, cylinder filling is improved which in turn leads better engine reponse and performance at mid and high rpm.

The kit includes:

- reed valve Evolution with carbon fiber reed petals
- aluminium mount for reed block
- rubber intake manifold 17.5mm / 21mm (type Dell'Orto)

Particularly suited for racing and "Hyper Racing" cylinders.
