Subaru Oil System Upgrade - Eliminate oil starvation in your WRX

Is an STi oil pan upgrade the best value in an oil system upgrade to prevent oil starvation for my WRX, at Stage 2 power levels on street tires?

The ’04 to ’05 STI and ’06+ 2.5L oil pans use a built-in sump; think of it as a built-in reservoir, that concentrates the oil closer to the pickup, making it more stable and less prone to oil flow fluctuations. Another advantage to using an STI oil pan is its more compact design, which offers additional clearance that can be used with a majority of aftermarket equal-length headers versus only a select few that can be used with the WRX pan. Follow along as we show you the basics on swapping out your own pan, installing a baffle plate, and replacing the oil pump pickup.

STI Oiling Parts List:
• ’04 - ’05 oil pan (Subaru PN 11109AA131)
• ’04 - ’05 dipstick (Subaru PN 11140AA120)
• ’04 - ’05 oil pump pickup (Subaru PN 15049AA070)
• ’04 - ’05 oil control tray baffle (Subaru PN 10915AA010)

I use an STi oil pan and I can say I have never had an oil issue and that is reving it out to 9k RPM...

I have a 2.5L oil pan (and KB pickup) simply so I can run an ELH if I chose to do so since most are not 2.0L fitment.
