O2 Sensor for my 1996 Honda Accord came on time exactly like A1 Auto said it would .
It fit perfectly this time around referring to the connector plug. Apparently the first one I ordered had a problem with the connector plug and it would not go onto my housing .This took care of my check engine light . Thanks A1 Auto.

2001 honda odyssey 02 oxygen sensor
I purchased this 02 oxygen sensor recently April '18 and it has worked really well so far. The only issue I had during installation and this is something I should have done was to measure the length of the wire on both the new and old parts. The new part I received from A1 auto was almost 2 inches shorter and made the connection almost impossible. I hope an improvement is done about this.

Smaller sensor than OEM
I purchased this to replace a malfunctioning upsteam oxygen sensor on my 02 accord EX Sedan.

Shipping was incredibly fast, arriving a day before their original estimate.

Installation went smoothly, but upon comparison it was clear that the sensor is significantly smaller than the OEM original. Luckily, the fittings were the same size and it still works. Only time will tell if this sensor will cause an issue (trouble code).

I deducted one star for the size difference and a second star because my order doesn't appear in my online account. Yet, when I use the "where's my order" feature, it shows all of the details.
