Mishimoto Red Aluminum Expansion Tank for 2017-2026 Honda Civic Type R and Acura Integra Type S (MMRT-CTR-17EMWRD)

Fits 2017-2026 Honda Civic Type R (including Limited Edition) and 2024-2025 Acura Integra Type S.

Replace the factory plastic expansion tank in your high-performance Honda or Acura with this durable, fully welded aluminum upgrade from Mishimoto. While the stock beige plastic tank is sufficient for daily commuting, it is prone to yellowing and eventual failure due to the extreme heat cycles found in the K20C1 engine bay. The Mishimoto Aluminum Expansion Tank is engineered to withstand high temperatures and pressure, providing long-term reliability for both track and street use.

This tank features internal baffling to ensure coolant stays near the overflow port during aggressive cornering, preventing unwanted air from entering the cooling system. A built-in sight glass allows for quick, easy monitoring of coolant levels without opening the system. Finished in a micro-wrinkle Rallye Red, it provides a clean, professional look that matches the Type R aesthetic while utilizing factory mounting points for a direct-fit installation.
