then ill replace the cat..

have you guys seen the prices for o2's.. 160 from dealer.. 80$ aftermarket.. anybody have any issues with aftermarket o2 sensors?

(its a 4 wire bosch universal)

Screw bosch! I put two of them on my car any they both threw up different errors. If you can get one for 160 from the dealer do it. They told me it would be $225 or so.
