🚀 High-Performance Denso 234-4153 Oxygen Sensor for Efficient Engine Performance Review

Perfect for exhaust pipe and plugs. The nuts holding the original sensor were completely rusted but I was able to loosen them. You will need to replace the nuts and use anti-seize nuts.

Worked great on my 1999 Toyota 4Runner 3rd Gen 3.4L v6 4x4 Automatic. OEM DENSO is the ONLY one recommended for these trucks as I've heard other brands of sensors can cause problems. Always use OEM for each sensor. They also came with a gasket that runs between this and your exhaust pipes. I installed new sensors for a fraction of what the dealer would charge and my truck is running perfectly again! Very happy! It should be noted that this is the bottom sensor.

Strange, both my car and my friend's truck had the same service trouble code issued the same month. We've replaced the downstream oxygen sensors on my Honda and his Toyota with matching Denso sensors and we've both had the same great results - no more check engine light (hate that light!), and both were smoke free a week after the replacement. Just make sure you get the correct sensor for your vehicle/year. It was a bit difficult to test this for a truck.

Had P0420 engine check code related to catalytic converter function on 95.5 Tacoma 2.4L 2wd with auto pickup. Since the truck had 163,000 miles I decided to replace the intake and exhaust O2 sensors with Denso OEM sensors to see if that was the problem. After soaking extremely rusty nuts in solvent, I easily removed what was left of the nuts. Surprisingly, the mounting bolts remained in good condition. I bought some new metric stainless steel nuts from my local hardware store and replaced both…
