Mishimoto Aluminum Coolant Expansion Tank 2002-2007 WRX / 2004-2016 STI
The Mishimoto Aluminum Coolant Expansion Tank for your 02-07 Subaru WRX or 04-16 STI. This is a 100% aluminum unit that is TIG-welded, and it improves the under-hood aesthetics especially when compared to the OEM unit. Over time and mileage, the OEM coolant expansion tank can fail due to years of temperature variances. The Mishimoto unit is super durable, and it looks great as well. This is a great automotive aftermarket upgrade for your racecar, rally car, overlander or daily driver.
- Direct fitment for 02-07 WRX models and 04-16 STI models
- 50% greater capacity than the stock plastic expansion tank
- 100% aluminum fully welded construction for maximum durability during repeated cold and hot transitions
- Leak-free welded barb fittings
- Fits with both stock and Mishimoto radiator caps
