Oxygen Sensor, Left Side, After Catalyst - Mopar (56029050AA)

Part of the emission system in your 2010 Chrysler 300, PT Cruiser, Town & Country, 2010 Dodge Charger and Dakota and 2011 Ram 1500, 2500, 3500, and Dakota is the oxygen sensor. Its job is to measure the oxygen concentration in your exhaust gas that comes from vehicle. This helps your vehicle run smoothly. If you need to replace this sensor, you want to use OEM parts that are of good quality and fit. WeRMopar.com carries OEM parts at steep discounts over the dealership prices without any quality compromise. You may save a couple dollars by using aftermarket parts, but you compromise on fit and performance by using a part that may not fit.

When you add exact-fit replacement parts from OEM, you know you are getting parts that are made to fit your vehicle's specifications because they are designed using factory specs. Aftermarket parts are usually universal fits, which makes them a part that may need to be modified to use. Some bolt holes may not line up or hoses may be too long in universal parts.

OEM parts are not rebranded parts that are the same as other aftermarket parts. While other aftermarket parts may all come from the same manufacturer and be put in different boxes, you know exactly what you are getting with OEM.
