Review on 🔬 Denso 234-4620 Oxygen Sensor: Precise Air/Fuel Monitoring for Enhanced Engine Performance by Brett Robinson

Fixed my gross idle and check engine light on a 1997 Accord. The wire is slightly longer than standard (maybe 1 inch) and fits perfectly. If you use a misaligned oxygen sensor shorting bushing, it will hit the heat shield. I had to remove the exhaust heat shield to get the old sensor out and this is the new one. If you use a tool with a longer head it will work just fine, but I didn't have one. This sensor looks almost exactly like the original. I will update when the mpg improves.
