2004 Civic O2 Sensor help/clarification

[gearbox]

nah the sensor only just got warm after about 20 secs, then i felt no difference. on hot days it prolly wont matter, but on cool days i will try and let it sit in on position for 20-60 secs. better than being cold.

i just let it sit for 20 secs in the on position til the engine light goes off, then i start and warm up like normal. i havent noticed any difference, so i think the exhaust gases get much hotter than the sensor. so i dont think it will do much other than a slightly faster warmup which isnt noticable.
