🚀 Enhanced Performance Denso 234-4659 Oxygen Sensor for Optimal Engine Efficiency Review

Worked great, still working great after 300 miles. It comes with all the lanyard and bottom grommet of a '97 Civic which is nice!

This was a direct replacement for my 2001 Acura Integra rear oxygen sensor. I used both the front and rear Denso sensors to troubleshoot the P0420 CEL code and the issue was resolved.

just replaced my downstream with my 2001 integra. Used denso for both sensors. Great replacement, both are easy to install. Finally my check engine light went out.

Even fits on the floor. Came with thread lubricant. All problems are solved, we had an acceleration error and reduced fuel consumption. With just one replacement this fault is gone, the engine is strong again so I expect an improvement in mileage as well.

I got this sensor 2 years ago on my 98 Civic, the engine light was on, this sensor is after the catalytic converter, I replaced it and the problem is solved , Emissions are gone, now I have to replace the upper sensor, the one on the exhaust manifold and I will go back to Denso. (Upper Sensor 02 - Denso 234-4099)

When I saw P420 (insufficient catalytic flow) code light on my 97 GS 1.8 Integra, (@ 135,000 miles) the dealer advised me to replace the 1st rear oxygen sensor. When I pulled the wire out of the bottom panel and found a 7/8" wrench it came loose easily. After installation the engine light was still on and showing another code or front sensor 02. I replaced the front sensor 02 and the problem was solved. These Denso parts are the closest thing to a dealer type, for less money and so far so good!
