Who actually makes the O2 sensors for the pre 2009 Vantages?

 

i recently had what i thought was an O2 sensor failure so i did some research on that part for my 2007 vantage. i'm pretty sure i ended up with evidence that the chinese automobile electronics company named denso was the manufacturer of the part. IIRC the denso part was about 20% that of the one that came in an aston box. not too surprising in that denso supplies a lot of electronics parts to a lot of automobile manufacturers the world over.

 

Good to know….thanks for the info..

 

NGK (via NTK) makes them. I did a ton of research looking for cost effective solutions to OE sensors, and spent a good amount of time on the phone with NGK directly.

I thought it was NGK. I had the same conversation with them also. But when you see the price of the O2 sensors at $100 or more it makes you wonder. I got all 4 sensors for around 200 US delivered from green spark plug in the UK. Also got NGK oem spark plugs for $108 delivered from the same place.
