EZ PASS™ Emissions Treatment | Catalytic Converter & O2 Sensor Cleaner | Emissions System Support | Smog Test Prep | 16 Fl oz, 2-Pack

EZ Pass™ Emissions Treatmentis a one-step emissions system and fuel system cleaner formulated to support catalytic converter efficiency and oxygen sensor performance. Designed for use prior to scheduled smog or state inspections, this advanced gasoline additive works through the fuel system during normal driving to help clean the catalytic converter, O2 sensors, combustion chamber, and fuel injectors.Carbon deposits, incomplete combustion, and exhaust system buildup can contribute to increased hydrocarbon emissions, catalyst inefficiency, and emissions-related diagnostic trouble codes. This emissions treatment is engineered to help reduce carbon buildup that may restrict exhaust flow or affect oxygen sensor readings. By supporting cleaner combustion and improved fuel system cleanliness, EZ Pass™ promotes smoother engine operation and overall emissions system efficiency when used as directed.Application is simple. Pour one 16 fl. oz. bottle into a full tank of gasoline (treats up to 16 gallons), then drive 10–15 minutes at highway speed with the engine fully warmed to allow the formula to circulate through the catalytic converter and exhaust system. For maintenance, use every 2,000 miles to help support long-term fuel system and emissions performance.Results vary based on vehicle condition and maintenance history. Severely worn or physically damaged catalytic converters cannot be restored by fuel additives and may require professional service or replacement.

• ONE-STEP USE. Pour one bottle into a full tank. This fuel system treatment helps clean the catalytic converter, oxygen sensors, combustion chamber, and injectors during normal driving.
• SMOG & EMISSIONS SUPPORT. Supports emissions system efficiency before smog or state inspections. Helps reduce carbon buildup that may contribute to increased exhaust emissions.
• OBD SUPPORT. Assists with certain emissions-related diagnostic trouble codes linked to catalytic converter and oxygen sensor efficiency when used as directed.
• ENGINE EFFICIENCY. Helps reduce carbon deposits that can restrict exhaust flow and impact fuel economy. Supports smoother operation and combustion performance.
• TREATMENT. Each 16 fl. oz. bottle treats up to 16 gallons of gasoline. Add to a full tank and drive at highway speed. Use every 2,000 miles for maintenance.
