Kawasaki Ninja H2 PRO RACE Lower fuel rail upgrade

Ninja H2 Lower Fuel Rail — Pro Race AN‑6 Version

A high‑flow, direct‑fit lower fuel rail engineered for boosted racing, high‑demand fuel systems.

Product Overview

This billet lower fuel rail is a direct replacement for the OEM Ninja H2 lower rail and mounts to the factory throttle body using OEM hardware. It accepts standard 11 mm O‑ring injectors and is fully compatible with both the OEM plenum and our H2O Intercooler Kit plenum.

Designed exclusively as a Pro Race configuration, this rail uses AN‑6 fittings to deliver maximum, unrestricted fuel volume to the injectors. With a 10 mm internal bore—over double the size of the OEM rail—it eliminates the risk of fuel starvation, even in high‑boost or E85 applications.

Important Notes

• This rail uses AN‑6 style connectors, so custom fuel hoses & fittings and our Pro Race upper rail are required. *NOT INCLUDED*

• Not a plug‑and‑play item; intended for extreme racing  high‑performance fuel system builds.
