my check engine light is on for a O2 Sensor. I forgot if it was the upstream or the other one. Hopefully its the easier of the two. I'll have Autozone rescan my car and tell me. But should i go oem which is over $150 or get an aftermarket one from Autozone? I think they only run like $50-$80

 

Might as well go OEM.

Alot of people here are against Bosh but really i never had a problem with it.

 

i would prefer OEM

I use NGK from sparkplugs.com. Can't go wrong with NGK.

 

i've been running a wakler o2 sensor from http://www.oxygensensors.com for a year now and so far no problems.

 

as long as they are good quality and come with the same number of wires/signals as the stockers, a universal/aftermarket will work just fine

$75 shipped for an OEM replacement.
