Review on 🔧 Enhance Engine Performance with Denso 234-9108 Air Fuel Sensor by Tim Roby

I saved $500-$700 by being able to order this and replace it myself. My 2013 WRX wasn't accelerating properly, bouncing around, from what I found online it was probably the O2 sensor. I took it to a mechanic and told him I think the O2 sensor needs replacing. They didn't agree, instead they changed all my fluids. Didn't fix the problem. I brought it back to them, they still didn't think it was an oxygen sensor, they changed the spark plugs for me. Didn't fix the problem. Told them I wanted to replace the O2 sensor, charged me $700. I told them I would try to do it myself, they said I shouldn't because maybe that's not what's wrong with him. Bought this O2 sensor and O2 sensor removal socket. After 2 hours the car works like new. It was quite an easy task and I will never go back to this mechanic.
