 Gas mileage improved
The removal and installation of this oxygen sensor wasn't too difficult. It required me lifting truck to install on exhaust side. This was performed while working on my back.

Easy install, just need to do a slight bit of welding and add in pipe if your old one has been stolen, with the use of a denso O2 sensor you will have no check engine light problems

Perfect fit, easy install
Just installed these 4 sensors on our 2013 cadillac escalade. Yes. They're always a pain in the butt to install, regardless of vehicle but they were perfect replacement parts. Installation took about an hour after putting vehicle on ramps. I highly recommend these!

Fits 2016 RAM 6.7L
Installed on 2016 Ram 6.7L. It takes time and a bit of YouTube research but definitely worthwhile. 6 months in and no issues or leaks. Fairly straight forward and easy if you are comfortable wrenching on vehicles. It's a great piece of mind not to have the failure prone EGR cooler on my truck any more. Bulldog and Magnaflow also installed.

Nice kit
All parts and pieces are good quality and install is relatively straightforward. The coolant line leaked at the o ring connection. I removed the supplied o ring and replaced it with the green factory one from the removed egr cooler and it seems to be sealing fine now. Instructions can be followed if you watch a video first to familiarize yourself with the process.
