Product Description

The Weapon R 826-122-102 Aluminum Coolant Overflow Tank is a high-quality replacement/upgrade tank designed to take the place of the stock plastic reservoir on *2008-2015 Mitsubishi Lancer Evolution X* models. Crafted from durable billet 6061 aluminum and precision TIG-welded, this tank offers superior strength and longevity compared to OEM plastic reservoirs that can crack or weaken over time, especially under high-performance or track conditions. 

Engineered for performance environments yet suitable for daily drivers, the Weapon R tank prevents coolant overflow and helps maintain proper engine cooling by safely capturing expanding fluid. Its vehicle-specific design aligns with OEM mounting points, allowing a straightforward installation without the need for vehicle modifications. The polished finish also contributes to enhanced engine bay aesthetics and durability under heat exposure.
