- Exclusive Flow Guide that better channels admission, reducing turbulence and load losses, key to stable and powerful performance.
- 360 ° rotary admission collectorcompatible with POLINI CP Carburetors 17 to 24 mmwhich allows both original and open filter to be assembled.
- Competition buttwith copper joint, double segment piston and several base joints (0.2 and 0.3 mm) to customize the Squish and refine the compression to the millimeter.
