Intake spacer Naraku Jet Flow aluminum CNC for 90cc 4-stroke tuning kits GY6, Kymco

You have already purchased the Naraku 90cc cylinder kit for 4-stroke engines and want to further optimize its performance?

With the intake spacer, CNC-milled from aluminium, you can increase the performance of your cylinder with minimal effort.
The conical passage narrows the cross-section (from 24mm from the intake manifold to 21mm at the cylinder inlet), which results in the so-called Venturi effect, i.e. the air-fuel is accelerated, which leads to a higher filling level of the cylinder and thus to more torque.

Technical data:

- Intake spacer Jet Flow Naraku, CNC-milled from aluminum, conical
- 24mm intake on the intake side
- 21mm exhaust on the cylinder side, marked by the groove for the O-ring seal
