Product Overview

This upgraded silicone radiator hose is a professional racing modification part specially designed for Kawasaki Ninja400 2018-2025. The original stock rubber cooling hoses are prone to aging, swelling, deformation and cracking under long-term high-temperature engine operation, causing coolant leakage, unsmooth circulation and engine overheating issues. This high-performance multi-layer reinforced silicone hose perfectly matches the original pipe routing and interface size of Ninja400. It effectively withstands extreme high temperature and water pressure, avoiding pipe bulging and coolant leakage, maintaining efficient and stable engine cooling circulation. Available in vivid bright red and racing green colors, it replaces the dull factory black pipes, greatly enhancing the engine compartment’s sporty and aggressive racing visual effect.
