WOw on the $425. it cost me $80 to change all 4. I used universal 4 wire o2's soldered up the wires and heat shrinked them to the old harness's. instructions are petty clear and easy to follow for the o2's. You may need a few tools. o2 sensor socket ($7.99-autoparts warhouse) 7/8 wrench(depends where you buy it), steel pipe 3 inchs or so in diameter atleast two feet long($19.99 Lowes or Home Depot) for leverage. (put wrench on o2 sensor, pipe on wrench) crank to break free and then unthread by hand. soldering kit (5.99 at walmart). I already had all the materials but even if I didn't it would only cost me $140 or so. takes me about 45 mins to do one o2 slaking off. 2 hours for all 4 (depends how long it takes to solder) I suggest a DIY $425 is a weeks pay for some people.
I replaced my front two on my '93 because the codes said they were gone. About $180 each tax in to buy. Installed myslef. Noticed no difference other than the ck eng. light going away.
