COBB Coolant Overflow Tank (800670) - 2022-2026 WRX
Upgrade your VB WRX engine bay with the COBB Aluminum Coolant Overflow Tank, designed to replace the brittle and unsightly factory plastic tank. Constructed from TIG-welded aluminum with internal and external anodizing, this tank offers an increased 1.1L capacity over stock while providing exceptional long-term durability. It features internally welded fill and vent tubes—with the fill tube extending to the bottom to prevent air ingestion—plus an integrated red anodized dipstick for quick coolant level checks. To complete the engine bay overhaul, it includes a windshield washer fluid filler neck finished with a blue anodized billet cap.
Emissions Note: This part is not an emissions-related part and therefore can be used on emission-controlled vehicles.
