About Competition Series EJ Oil Pan
The IAG Competition 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. The 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 design incorporates cooling fins to aid in dissipating heat from the oil as air passes over them. 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 oil drain plug uses an OEM style crush washer. The oil pan is also threaded with 1/8th inch NPT port to accept many popular oil temperature sensors. 1/8th inch NPT plug is also included in the event that the sensor port is not used.
The upper flange mounting surface is CNC machined for better hardware fitment. The flange features a sealing O-ring for easier installation and removal. 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.
About Competition Series Oil Baffle
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 Competition Series Baffle should be used in vehicles that will see track time, however, it is acceptable to run this baffle on the street as well. The Comp Series baffle is configured with Viton one-way flapper valves which hold oil in the area closest to the pickup. Combining the baffle with the 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.
About Windage Tray
The job of the windage tray is to help direct oil from the upper crankcase down into the lower crankcase and oil pan area. Manufactured from stainless steel, precision-formed louvers direct oil downwards and help to prevent oil that is draining from the cylinder heads in the lower crankcase area from sloshing upwards into the path of the crankshaft and connecting rods, thus reducing aeration.
About IAG V2 Oil Pickup:
The IAG Performance Subaru WRX / STI oil pickup is designed to replace the OEM EJ25 oil pickup which is prone to failure. It's a well-known fact that the OEM oil pickups often crack and fail which in most cases destroys your motor from lack of oil pressure. To avoid the cracking failures seen in the OEM oil pickup tubes, the IAG oil pickup is manufactured from heavy-gauge steel tubing that is 2x thicker than OEM. Additionally, it features a flange machined from 3/8" stainless steel to mate with the block, sealed with a Viton O-ring. The integrated heavy-duty stainless steel mounting bracket uses two mounting points rather than the OEM single mounting point. Furthermore, the oil pickup features a formed bottom with an OEM style mesh screen for proper filtration. The TIG-welded oil pickup increased material thickness matched with the two-point heavy-duty mounting bracket helps ensure it does not fatigue and fail over time like an OEM unit.
