has anybody swapped in an aftermarket Bosch unit instead of the $200 stock replacement? Got a P/N? I need to do a test on my front one and I'd be much happier spending $50 than $200.

 

i found rockauto.com (never heard of them before this) has ac delco (part # 2132908), Dephli (part # ES20222), as well as the Bosch (part #13878). Ive never dealt with this place before, but it may be a starting point.

 

did you order one and successfully use it?

 

Rock Auto is a good place. I have ordered things for my Subaru from them. They have some good deals.

 

amazon has the bosch for a few bucks more and their return policy is quite generous. that might be my answer right there

 

I purchased the Delco unit from Rockauto to replace my front O2 sensor. No issues, no CEL, even after a 125 mile track day.
