Mishimoto Black Aluminum Coolant Overflow Tank for 2008-2016 Subaru WRX / STI (MMRT-STI-08BK)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2008-2016 Subaru Impreza WRX, WRX STI, and WRX/STI models.
Replace the failure-prone factory plastic reservoir with the Mishimoto MMRT-STI-08BK Coolant Overflow Tank. Stock plastic tanks are notorious for cracking and leaking after years of repeated heat cycling. This Mishimoto upgrade is engineered from durable, TIG-welded aluminum to provide long-lasting reliability and a clean, professional look in your engine bay.
This overflow tank features an integrated CNC-machined dipstick, allowing you to quickly and accurately check coolant levels without guesswork. Designed for a direct-fit installation, it bolts into the factory location and is fully compatible with both the OEM radiator and Mishimoto performance aluminum radiators. The black anodized finish provides a sleek, stealthy appearance while resisting corrosion.
- Direct fit for 2008-2016 Subaru WRX and STI
- Durable TIG-welded aluminum construction
- CNC-machined dipstick for easy fluid level monitoring
- Anodized black finish for superior corrosion resistance
- Installation completed in under 30 minutes
