By supplying two upstream (pre-catalytic converter) and two downstream (post-catalytic converter) sensors, the kit helps your vehicle maintain proper air-fuel sensing and emissions monitoring when original sensors fail or age out. Each sensor is supplied with OEM-style connectors and a one-year quality guarantee — verify vehicle compatibility using the \"Select Your Vehicle\" tool before purchase.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines does this higherbro O2 sensor kit fit?\u003c\/h3\u003e\n\n\u003cp\u003eThis kit covers a broad range of Dodge, RAM, Jeep, and Chrysler models and engine sizes across multiple model years. It lists compatibility for many Ram 1500\/2500\/3500, Jeep Grand Cherokee\/Wrangler\/Liberty, Chrysler 300\/Town \u0026amp; Country, and Dodge Grand Caravan models.
