Cobb 22-23 Subaru WRX Coolant Overflow Tank

This upgraded Subaru coolant overflow tank (1.1L capacity) improves both form and function. Constructed of welded, anodized aluminum, it's suitable for stock cars or modified vehicles, adding style and convenience to the engine bay. The OEM plastic tank is prone to cracking from heat and has an obtrusive shape. The COBB Overflow features internal and external anodizing for durability, internally welded fill and vent tubes for a leak-free design, and a fill tube extending to the bottom to prevent air ingestion. The vent tube exits through the bottom for routing out of the car with included silicone tubing. An integrated red anodized dipstick allows for quick coolant level checks. It includes an injection-molded plastic reservoir cap and a blue anodized billet cap for the windshield washer fluid fill tube.
