This product was designed to create more space in the engine compartment. Combining two reservoirs into a single component frees up space for intercooler tube placement, easier maintenance, access to the engine, and durability.


  • The OEM plastic reservoirs are replaced with CNC laser cut and formed aluminum that is hand TIG welded to provide reliability under the most severe conditions.
  • CNC machined cap retainers assure these caps will never pop off.
  • All fittings and hose are DOT approved, meaning they cost more, but are actually designed to provide reliability under extreme temperatures and chemical exposure.
  • Designed to work with 2008+ WRX/STI models
