....an o2 sensor that is made for your car. i got prices for universal ones for my gsr (4 wire) ranging from 39.95-89.99 and i got prices for ones that are for my car ranging from 150-262.95. is there any difference b/w a univeral one and one made for my car?? if there is, is it worth the extra price???

I've read that the Bosch ones make the car run a little bit richer than the OEM part would. No confirmation of this though
