Mishimoto Polished Aluminum Coolant Overflow Tank for 2008-2016 Subaru WRX / STI
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2008-2016 Subaru WRX and WRX STI.
The factory plastic coolant overflow tank in the 2008-2016 Subaru WRX/STI is a common failure point. Over time, repeated thermal expansion and contraction cycles cause the stock plastic to become brittle, leading to cracks, leaks, and a yellowed, unsightly appearance in the engine bay. The Mishimoto MMRT-STI-08 Coolant Overflow Tank provides a permanent solution, replacing the failure-prone plastic unit with a durable, TIG-welded aluminum reservoir designed for longevity and performance.
- TIG-welded aluminum construction for maximum durability through repeated heat cycles
- Integrated CNC-machined dipstick allows for quick and accurate coolant level checks
- Polished finish provides a significant aesthetic upgrade over factory plastic
- Direct-fit installation takes less than 30 minutes
- Compatible with both factory and Mishimoto performance radiators
- Manufacturer Part Number: MMRT-STI-08
- Mishimoto Lifetime Warranty
Includes: (1) Aluminum Tank with Polished Finish, (1) CNC-Machined Dipstick.
