Would like to replace the O2 sensor in my car and I'm seeing a large variation in prices online.

$188.50 (on backorder) at Centerline

$167.60 at Vick Autosports

Oxygen Sensor, Spider, Milano, 164 - (SKU 33-2885) [33-2885] - $167.60 : Vick Autosports, Fiat & Alfa Romeo Parts

down to $76.97 from Summit Racing for what they say is the Bosch OEM unit.

Why so much price variation? Is there a particular Bosch part we need to get?

thanks,

The three-wire sensors are all pretty much technically the same. The difference is in the wire lengths and connectors.

The direct-fit Bosch versions have the right plugs and wire lengths, but tend to cost a lot more. If that Summit Racing one is actually a direct-fit for the Milano it's a pretty decent deal.

The cheapest option is the Bosch universal three-wire sensor. It doesn't have the plugs: it comes with a splicing kit that you use to splice to the plugs you cut off your existing sensor. These are usually what I buy as it's easy to do and it's the cheapest option (usually $30-40).
