Denso 234-9148 Air Fuel Ratio Sensor - High Performance Oxygen Sensor for Toyota, Lexus, Honda - Improves Fuel Efficiency & Engine Performance (Ideal for Off-Roading, Daily Commuting & Performance Tuning)

I consider myself a DIY type of dude and I took this project on. I did look at 1 video with a similar drive train as my truck (Nissan vs Infinity) and following his instructions, I was able to change out both O2 sensors on my truck. The driver side was the hardest but I got through it. The passenger side was a lot easier and took half the time to change them out.If you are a DIY and looking to change out your O2 sensors because you got that pesky engine light on your dashboard and your plug in sensor gives you that PF something code, get the DENSO line of O2 sensors.
