WRX Catchcan and Billet battery bracket
This system was developed specifically to fit the WRX / STi and is supplied as a complete kit. The WRX catchcan we believe is a critical system to separate oil and assure it is not ingested into the intake tract. On all the vehicles we have completed upgrades, the amount of oil in the Intercooler, manifold and intake tract without a catchcan system is always a surprise.

On the MY06-07 STi prepared for the Dutton Rally, we inspected our catch can system after the event. The catch can was approx 1/3 full of oil. Our design incorporates an Oil Air separator, baffle and no vent direct to atmosphere (apart from entry into the intake which is open to atmosphere via the Air Inlet filter). This assures emission compliance. The Hyperflow catch can system has been upgraded for the MY06-07 WRX / STi. We now run dual hoses back into the inlet tract to assure improved air flow. A supplementary bracket and extension piece properly locate the filler neck for the Headlight washer container. The Hyperflow Catch can system provides proven performance and a high quality finished look to your engine bay.
