As the rubbers cure they can give off acids which eats at the steel and affects the seal.
Well, like I said, if the Toyota filter works well for you, then stay with it. I've been trouble shooting this problem for 9+ years with my Tundra on cold or warm mornings. Now that I've narrowed it down to a single variable, the engine oil filter is the common denominator. I won't waist my money on anymore Toyota filters for this truck.
