Upon further review, I'm good with running the factory housing with a Donaldson P502503 filter.

Im not running a high power 6.7 truck, say Like in the SPE dragster, so I'm thinking I'm good.

But I am still considering the SPE oil pan though...

More flow through the bypass system is not a good thing.
That's what I was thinking... too much flow through the bypass filter system.
