Cataclean 2pk of 16oz Bottles Fuel/Exhaust

The Cataclean 2pk of 16oz Bottles Fuel/Exhaust by MR. GASKET is a dual-chamber fuel and exhaust system cleaner designed for mechanics and automotive enthusiasts who demand optimized engine performance and emissions compliance. This two-bottle set addresses carbon buildup in both the fuel injectors and catalytic converter—two of the most critical restrictions that compromise horsepower, throttle response, and fuel economy. Whether you're troubleshooting rough idle, failed emissions tests, or simply maintaining a high-mileage engine, this product delivers the chemical intervention modern fuel systems require.

Each 16oz bottle is formulated to dissolve stubborn carbon deposits that accumulate over thousands of miles, particularly in direct-injection engines and vehicles running on ethanol-blended fuel. The fuel system cleaner targets injector tips and intake valves, while the exhaust cleaner works downstream to restore catalytic converter efficiency and reduce harmful emissions. This approach mirrors professional shop protocols: rather than rely on detergent packages in pump gasoline, serious mechanics add concentrated cleaners to ensure complete combustion and proper oxygen sensor readings. The two-bottle format allows you to treat the fuel system during one service interval and the exhaust system during the next, or combine both for a comprehensive clean on high-performance or problem vehicles.

This product is ideal for gasoline engines with conventional port injection or direct injection, diesel applications, and any vehicle exhibiting hesitation, hard starting, or elevated emissions levels. Installation requires no tools or mechanical expertise—simply pour the appropriate bottle into the fuel tank or directly into the fuel system (fuel treatment) or add to the exhaust fluid system per manufacturer guidelines. Mechanics working on fleet maintenance, enthusiasts preparing vehicles for dyno testing, or DIY technicians addressing performance complaints will find this two-pack cost-effective and results-driven for restoring baseline engine efficiency and passing state emissions inspections.
