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.
