I'm glad I went with this style vs the socket style. It's clear that this is a much more versatile way of getting into tight spots. This made changing my O2 sensor a breeze. The whole process took less than 5 minutes. This tool made changing the upstream O2 sensor simple and it is the only tool that will fit for changing the downstream/aft O2 sensor. If I had purchased a socket style socket I would have still had to purchase this one for my aft sensor anyway.

I'm happy I decided to change the O2 sensor at the same time as changing the plugs on this car for my 100K service. The O2 sensor is right in the way of the #6 plug so changing the O2 sensor was a no brainer. It had to be removed to get that plug wire off anyway. Most people don't realize that the O2 sensor is a wear item just like their spark plugs and don't change them out every 100K. By the way, before anyone comments on my 100K tune up, please be aware that my vehicle used Iridium spark plugs that only need changing at 100K miles. Amazon saved me a ton of money on my O2 sensor too!

I had no idea that my car wasn't performing at 100% until changing the plugs, wires, and O2 sensor. It idled smooth and had tons of acceleration, so I didn't notice anything wrong. By looking at the plugs that came out with 100K miles on them you would never know it. They looked almost new (The OEM Iridium plugs are awesome). However it runs like a Singer sewing machine now, and I wish I would have done this 10K ago. It's certain in my mind that this improvement is due more to the O2 sensor replacement than the plugs.

Now if I can find a tool that makes getting those plug wires off easier. My arms are a bloody mess after wrestling with the plug wires between the engine and firewall on that car. My old plug wire pliers just didn't cut it for this application.
