Product Questions & Answers

Q:Is this upstream or downstream?
Nef79
A:BEST ANSWERHi Neftaly, I'm glad to assist you. This is a wideband and heated type of universal oxygen sensor. This is commonly used for the front or rear location and you will need to reuse your original connector after some splicing and cutting. Please provide your complete vehicle application and engine size (year, make, model, submodel and engine size.) so we could identify the correct direct fit oxygen sensor for your car. Take advantage of our clearance sale for this part while supply lasts. I hope this helps. Happy shopping. https://www.carparts.com/oxygen-sensor/walker-products/wkp350-34200?can=CPJE1043 Show less
