OTL Billet Coolant Expansion Tank - Subaru WRX 2002-2007 / STi 2004-2021
The OEM tank is big, bulky, and is prone to cracking at the fittings causing leaks. Aluminati set out to fix this issue with a 100% CNC machined billet aluminum tank with no welded parts! They mount directly to the OEM mounting points and use the same OEM hoses. It was designed to look great and to be tucked into the manifold as far as possible. With the tank being mounted higher than the radiator, this helps in burping the air out of your system unlike the OEM tank. Replace your’s today before it becomes a problem!
