2008-2018 Audi Q5 8R/8RB NOX-sensor 8R0907807G 8R0907807Q

When I received this product, I was impressed with the overall quality and fit. It installed perfectly between my O2 sensor and the bung on my downstream catalytic converter. Unfortunately, my CEL came back on after I had cleared the code and drove for a few hours. I've heard from other people that it does what it is claimed to do. However, my 2008 Subaru Forester with aftermarket catalytic converters did not respond. Maybe it will work for someone else. Since the price was low and it didn't hurt anything, I'm just leaving it in place.

So far so good easy to put together and I liked the different size options

Excellent product. Order process, delivery coordination are perfect. Thank you.

Simple devise, works great, jeep runs smooth.

Spacers are of high quality. Also fixed my CEL immediately after installation. Thank you again and will definitely return!
