Upgrade your Ford Focus RS or ST with the Mishimoto Aluminum Expansion Tank, designed to enhance engine bay aesthetics and reliability. Constructed from durable TIG-welded aluminum, this tank offers superior longevity compared to the stock plastic unit, which can degrade over time due to temperature fluctuations. The Mishimoto tank features internal baffles that prevent coolant starvation during aggressive driving, such as high-speed cornering, braking, and acceleration, reducing coolant sloshing and maintaining optimal engine cooling efficiency. The inclusion of a sight tube allows for easy monitoring of hot and cold coolant levels, simplifying routine maintenance and ensuring your cooling system remains in top condition.
Designed for quick and precise installation, this expansion tank can be fitted in under one hour, thanks to its perfect fitment tailored for 2013-2018 Ford Focus ST and 2016-2018 Focus RS models. It reuses the stock cap and includes an overflow nipple on the fill neck, enabling the addition of an auxiliary coolant tank to keep your vehicle NHRA compliant. The Mishimoto aluminum tank is available in three aesthetic variants—black, wrinkle red, and wrinkle nitrous blue—allowing you to customize your engine bay to match your style. Each option complements the vehicle’s performance while providing a clean, professional look.
Designed with both functionality and style in mind, this expansion tank is an essential upgrade for serious enthusiasts seeking improved cooling system performance, durability, and a sleek appearance. Backed by Mishimoto's lifetime warranty, it is a reliable choice for enhancing your vehicle’s engine bay and maintaining peak performance under demanding driving conditions.
