Ive seen a bunch of people talking about turning the ignition on (without starting the engine) and letting the o2's "warm up" for 45-60 seconds, THEN starting the engine. A bit inconvenient, but after recently having to replace o2's myself, I'm going to give it a try.

I had stock sensors btw. Lasted about 3k miles.
