Mishimoto Silicone Hose Kit Blue 2017 Plus Civic Type R

Mishimoto Silicone Hose Kit for the 2017–2021 Honda Civic Type R replaces factory radiator hoses to increase heat and pressure tolerance for more reliable cooling under sustained load.

This hose kit is engineered specifically for K20C1-equipped Civic Type R models and provides a direct-fit upgrade to the stock rubber plumbing while adding a durable, color-matched finish to the engine bay.

Key features and why they matter

• Vehicle-specific fitment for K20C1 engines — Ensures correct routing and secure connections without modification, preserving OEM fitment and serviceability.
• Silicone construction — Offers improved resistance to heat and pressure compared to stock rubber hoses, reducing the risk of swelling, softening, or collapse under high thermal load.
• Blue OEM-style appearance — Adds a clean, factory-inspired visual upgrade to the engine bay while remaining compatible with OEM clamps and hardware.
• Direct replacement for stock radiator hoses — Simplifies installation with like-for-like connection points and maintains proper coolant flow characteristics.
• Mishimoto engineering and validation — Backed by Mishimoto’s reputation for motorsports-grade cooling components, supporting long-term reliability in performance applications.

Performance and functionality

This kit targets the radiator plumbing on Civic Type R models equipped with the K20C1 engine. By substituting silicone hoses where the factory used rubber, the system benefits from greater thermal stability and improved pressure handling during aggressive driving or heat-soak conditions. The direct-fit design preserves coolant routing and service access while providing a durable replacement that resists common failure modes of aged rubber hoses.

Ideal for: Owners seeking a durable, OEM-compatible coolant hose upgrade that maintains factory fitment and increases resistance to heat and pressure without modifying the vehicle.
