Venturi Big Throttle Body - CR-Z ZF1

Developed from extensive testing of throttle body shapes to achieve the greatest effect. The Spoon throttle body increases efficiency with a venturi shape and a polished surface to reduce air resistance. A larger diameter throttle butterfly is used to complement the larger opening and has the same durability as the OEM material. The throttle body opening is increased from 62φ to 70φ and the butterfly opening is increased from 62φ to 65φ. Power output is increased along with throttle response. Gasket is included.
