Review on Aintier O2 Oxygen Sensor Set for Jeep Dodge Chrysler Wrangler 3.8L/Grand Cherokee, Charger/Ram 1500 4.7L/Magnum/Dakota/Durango/Sebring/300 - Front Rear Upstream Downstream | 2pcs by Brandon Show

friends, do not waste your money. I installed these new O2 sensors in my daughter's car just in case she had a P0420 code problem (catalyst system) but after about 50 miles they triggered 3 other critical trouble codes and put the computer into limp mode which caused the car stopped. Twitched furiously, misshifted and burned 1/4 tank of gas in just 9 miles before she could bring it back to me. Don't risk it, you don't want them to fail along the way. And like my daughter, you probably can't afford to wait for new ones only to risk failing again with those new ones.
