350-35046 Oxygen Sensor, Original Equipment Replacement Premium O2 Sensor,Premium Oxygen Sensor

Did your MPG got reduced?Mine did and honestly very quickly, including having mort loud and shaky running engine to the point that even women noticed it.A every person who had a brand new car you going with your complaint to the dealer...., but dealer says that computer doesn't report any code = no issues. To try to learn what it may be the hidden cause you should understand how modern gas engines are built. They are built to be more efficient, but struggle to performing that way in long run and are not to built to last,.. only survive the 60K warranty.What I learn is that you can't have the engine oil in use for more than 5k. The carbon sludge and build up creates very quickly. So my first approach to solve the mpg was using additives into gasoline to clean the engine system..... it gasped a lot at first. Than the mpg went v up and down again, so I did engine oil flush, which jeweled tremendously. Car engine was immediately quite a it was at the day of purchase and mpg improved again. I was using the gasoline additives almost regularly as a precautions. At about 30k the mpg got very bad, almost 50% down. At this moment I considered to do tune-up, but first the simplest it seemed to try install new oxygen sensor even that car PC did not noticed anything wrong with it.The car has 11-13mpg driving in the city before changing the sensor. Nie it has 21-22mpg.I changed the oxygen sensor 1st time in my live and considering myself very handy and technically smart, I must say that it wasn't the worst thing to loosen it up with proper tools, but instead it was the wiring connector which gives some challenges (in my case). I had to remove cable brackets, connector bracket and cut out original zip-tie cables and then everything was easy and smooth work.Bottom line if your car mpg worsen a lot give this thing chance. I will still do a tune- up on my car as it hit already 40k. I insurgency few spark plugs (the way one to reach) and they already showing signs of being on the last leg.

I installed it the day I got it.. The wire was a lot longer then the OEM” one but should not be any trouble if you keep it away from exhaust manifolds and pipes.. After I installed it I ran a check on it with a GOOD scan tool to see what it was reporting?... All is working to OEM’ Spec and a test drive (Pasted) it ECM test.. Time will tell but so fare works GREAT!! 👍👍👍👍👍👍

the part fit exactly for my 2013 Elantra, in my case the position of the sensor is at the lower rear of the engine, I was afraid that the cable length would be too short but it fit perfectly and is up to 1 inch longer than the original. RECOMMENDED

Bought this O2 sensor to repair a code my 2013 VW tiguan was throwing which was a P0030 (Bank1 Sensor !). Has been running good after install. No more check engine light.

worked perfectly,,car has stopped dieing

Excellent product. Had a P0300 code (oxygen sensor bank 1, sensor 1) on a 2014 VW Jetta and this little unit fixed that right up. Saved lots of $$! Happy customer!

Nobody wants to wire their own oxygen sensor. This is probably a great quality sensor, but first off you need to color your wires the same as the factory unit. Second, the instructions are insanely bad. It's 3 wires. I'm sure you make the original sensors for the car manufacturers, make the replacement simple to figure out.

Was elated to find this item on Amazon with a price significantly less than the local auto parts stors. The part was a cinch to install, and the sluggishness in the car went away.
