Mini Cat 90° Exhaust Pipe O2 Sensor Spacer Adapter Catalyst Simulator Check Engine Light CEL Eliminator P0420/P0042/P0430

Why do you need to replace the oxygen sensor?

• A worn-out oxygen sensor can lead to increased gasoline consumption, higher exhaust emissions, accelerated damage to the catalytic converter, and various engine performance issues.
• In regions with emissions regulations, a faulty Check Engine Light (CEL) and O2 sensor can cause inspection failures. Our Mini catalytic converters can resolve these issues, allowing your vehicle to pass inspections smoothly.
• Replacing the oxygen sensor is an effective solution for resolving P0420, P0042, and P0430 fault codes.
