as with tires and allignments these cars are sensitive to the O2 sensors also. I do beleive some have tried universal sensors and had issues. personally I would pay the few extra $'s in this case for a good sensor as it will have a direct effect on gas milage, and you could save money there is the car is running its best, but that is your call
