These plug-and-play sensors replace both pre- and post-catalyst units to help the engine control module receive correct exhaust-oxygen data. That supports smoother idle, more consistent fuel trims, and better emissions behavior when installed on matching applications.\u003c\/p\u003e\n\n\u003ch3\u003eWill this kit fit my Jeep Wrangler or other vehicles?\u003c\/h3\u003e\n\u003cp\u003eThese two sensors are designed for a long list of late-1990s to 2000 vehicles with specific engines. Confirm fit by matching your vehicle year, make and engine size—common fits include Jeep Wrangler 2.5L and 4.0L, Jeep Cherokee\/Grand Cherokee 4.0L, and many Dodge, Plymouth and Chrysler models from 1995–2000.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits Jeep Wrangler 1997–1999 (4.0L) and 1997–2000 (2.5L)\u003c\/li\u003e\n  \u003cli\u003eCompatible with Chrysler Cirrus, Dodge Stratus, Plymouth Breeze 1996–2000 variants\u003c\/li\u003e\n  \u003cli\u003eAlso fits multiple Dodge Ram and Dakota years and engine sizes listed for 1995–2000\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do upstream and downstream sensors differ, and why replace both?\u003c\/h3\u003e\n\u003cp\u003eThe upstream (pre-catalyst) sensor measures raw exhaust oxygen to guide immediate fuel trim adjustments. The downstream (post-catalyst) sensor monitors converter efficiency.

After install, the engine may run briefly through adaptive fuel trims as the ECU relearns, and any stored OBD-II codes should clear once conditions are met.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRequires basic hand tools and a sensor socket or wrench\u003c\/li\u003e\n  \u003cli\u003eAllow the vehicle to complete a drive cycle for ECU relearn\u003c\/li\u003e\n  \u003cli\u003eCheck and clear codes after installation if your scan tool allows\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat quality and warranty support comes with the higherbro sensors?\u003c\/h3\u003e\n\u003cp\u003ehigherbro backs the sensors with a one-year unlimited-mileage quality guarantee to protect against manufacturing defects.
