Oxygen Sensor

A small vehicle component that makes a big impact, oxygen sensors control or contribute to several vital engine functions including fuel/air mixture, timing and emissions. Known to fail anywhere between 30,000 and 100,000 miles, it’s always a good idea to have a replacement O2 sensor on hand for when the time comes. Replacing a faulty oxygen sensor is an easy, DIY job that can ensure peak performance, along with savings at the pump, in just a matter of minutes.
In this day and age, it's increasingly important to be responsible about the amount of emissions your vehicle produces. By feeding data to the engine control unit (ECU), your vehicle's oxygen sensor helps your engine run as efficiently as possible, while producing as few emissions as possible. If one or more of your ride's O2 sensors is not functioning properly, not only will you fail any emissions tests, but you're throwing gas money out the window and possibly causing damage to your catalytic convertor. Maintain your emissions and fuel systems with a replacement oxygen sensor from AutoAnything and save even more with our 1-Year, Lower Price Guarantee.

BBK O2 Sensor Extensions

Life saver

I ordered a set of jba high flow catted mid pipes and turns out the O2 bung was just a little further back down the pipe so it cause my O2 plugs to be stretched as tight as possible. These extensions snapped right in and made plenty of slack in my plugs. They are worth the money if you decide to upgrade grade your exhaust. View more reviews...
