No issues for Chrysler Town and Country
Used these to replace bank 1 upstream and downstream sensor for my 2015 Chrysler Town and Country 3.7L. So far so good. Will provide and update if things turn out differently.

Great Buy
Product had âalready antiseezâ on threads which the installed was a bit challenging. Works like it should. fit perfectly.You will have to apply pressure with your fingers to tighten the O2 Sensor. I recommend to use the special made socket for it as well.

Looks well made
Looks very good quality and value. I have not fitted it as my problem cleared after fixing a leaky water hose, I suspect it was somehow dumping too muck moisture into the exhaust system ⦠causing the issue

Works as they should!
Worked perfect replacing the 2 upper sensors on my 04 Grand Cherokee. Will they last as long as Mopars? Dunno, but they are working exactly as they should according to my scanner, so thumbs up from me!

Well if your like me your not interested in paying 200$ plus in labor fees for something you can do yourself, I got a 2020 Grand Caravan GT, 50 thousand KMs from a dealership and ofcourse… drive off the lot almost home and check engine light on, threw on scanner , said bank 1 sensor 1, couldn’t find exactly that on Amazon, do took a chance on this one and if your in my boat this works for bank 1 sensor 1 !!!
