do the front o2s play a huge role in the performance of the car? i know this might sound like a noob question but i dont want to go and waste my money.the reason i need to change them is when i put the o/r h on the both got twisted some how and pulled one of the wires loose from the sensor.
yes you need the front ones, get the motorcraft replacement not the bosche ones. the motorcraft ones work best out of all the others, they dont cost a ton either.
Ya pretty much they are a huge part of the performance of the car, f buy bosch ones there just as good but dont even think about universal if they offer them at parts house Posted via Mobile Device
the motorcraft are narrowband, the bosche aren't. people have had problems in the past with the bosche, myself included. its your call, i think the denso ones are pretty much identical to motorcrafts.
