The Mishimoto MMTS-CIV-06 is a high-performance racing thermostat designed specifically for the 2006 Honda Civic SI. This thermostat is a crucial component in maintaining optimal engine temperature, ensuring optimal performance and longevity.
Unlike the stock thermostat, which often fails to properly regulate engine temperature due to its inability to open fully until the engine reaches a high operating temperature, the Mishimoto racing thermostat features a faster-acting, 160-degree Fahrenheit (71.1-degree Celsius) opening temperature. This allows coolant to flow more quickly to the radiator, reducing engine heat buildup and improving drivability, especially during high-load situations such as track driving or aggressive acceleration.
Made from high-quality stainless steel, this thermostat is both durable and corrosion-resistant. It features a 10.5-degree angle cut for a more secure installation and easier clearance in tight engine bays. The MMTS-CIV-06 also includes an O-ring for a leak-free installation and comes with installation hardware.
In short, the Mishimoto MMTS-CIV-06 is a must-have upgrade for any 2006 Honda Civic SI enthusiast looking to improve their engine's performance, reliability, and longevity. With its fast-acting design, high-quality materials, and easy installation, this thermostat is sure to provide you with the confidence and peace of mind you need to push your Civic SI to its limits.
