So I need a new lambda sensor and I have to choose between two brands Bosch and NTK/NGK. I think that Bosch product quality isn't as good as it used to be, but they invented the lambda sensor.

NTK instead should be Made In Japan, which means high quality, probably..

What should I choose?

Hi mate

I have worked @ a motor factors for over 5 years and i have never seen a NGK/NTK lambda sensor come back under warranty .

Hope this helps

col

yes, it helps a lot. thats what I wanted to hear.

Thanks mate!

Ntk are my best sell at gsf

Bought an Bosch sensor for just 26 lats which is around 31 pounds.

There's a trick with those Bosch sensors.

The one which I bought is an actual sensor for LADA cars. Sounds funny, but the sensor is completely the same as any other Bosch sensor, except connector. And as it's considered as an LADA part, this sensor is a lot cheaper than equivalent VAG part.

As I'm reading on Audi forum, this should work.

I will update this post how it all worked.

By the way, here's part number-

0 258 005 133

Everything is running fine. Connected together five wires and thats all.

So, if you want to save a few quid on a lambda sensor not saving on quality, just get the Bosch sensor for LADA.
