Through the use of Viton one-way flapper valves on our baffle and louvers in our windage tray, oil is prevented from reentering the upper crankcase area and is directed down into the oil pan to ensure plentiful supply to the oil pickup. The IAG Competition Series Oil Baffle is designed to limit potential blow-by and prevent oil starvation in your Subaru’s WRX / STI EJ engine during high rpm and high g-force driving. The pan is designed to use the included OEM style Viton dipstick o-rings with a unique chamfer to aid in the installation of the dipstick. The flange features a sealing O-ring for easier installation and removal. The upper flange mounting surface is CNC machined for better hardware fitment. A ⅛ inch NPT plug is also included in the event that the sensor port is not used. The Street Series Oil Pan is also threaded with a ⅛ inch NPT port to accept many popular oil temperature sensors.

The oil drain plug uses an OEM style crush washer. The included oil drain plug is integrated into the lower cooling fins at the absolute bottom of the pan to make sure all the waste oil is removed during maintenance changes. The design incorporates cooling fins to aid in dissipating heat from the oil as air passes over them. The Street Series cast aluminum oil pan was designed with fitment for a larger variety of popular headers in mind, while still increasing oil capacity up to 30% over OEM. The IAG Street Series Oil Pan for the Subaru WRX and STI is uniquely designed and CNC machined to suit a wide range of street and track applications. IAG offers our V2 Oil Pickup, Competition Series Baffle and Windage Tray combined with our New Oil Pan as a complete package.
