⚠️ Ensure the catalytic converter is intact. This product is highly effective for cleaning but will not repair a cracked, broken, or melted catalytic converter.
PROFESSIONAL-GRADE DPF & CATALYTIC CONVERTER FOAM CLEANER — Trusted by thousands of diesel specialists. This German-engineered spray foam dissolves heavy soot and carbon buildup inside your DPF or catalytic converter without any disassembly.
NO REMOVAL REQUIRED — Clean through the O2 sensor or temperature sensor port using the included long-reach nozzle. Spray, soak 20-25 minutes, reinstall sensor, and drive. Saves $500-$2,000 vs. professional DPF cleaning services.
WORKS ON DIESEL, GAS & HYBRID VEHICLES — Unlike fuel additives that only work on mild buildup, this direct-spray foam penetrates and dissolves even severely clogged filters. Use on DPF filters, catalytic converters, and EGR valves.
RESTORE FULL ENGINE POWER & FUEL ECONOMY — A clogged DPF triggers constant regen cycles, kills fuel economy, and robs horsepower. Our foam cleaner restores flow, reduces regen frequency, and brings back the performance you're missing.
Use regularlPAIRS WITH DPF PURGE ADDITIVE (SKU 808) — After foam cleaning, maintain results by adding our DPF Purge fuel additive every 3,000 miles. This preventive maintenance combo keeps your DPF clean and avoids the $3,000-$8,000 DPF replacement cost.y MotorPower Care DPF Foam Cleaning to maintain a proper operating emission system.
Complete Kit: Includes Catalytic Converter Cleaner Fuel Additive, Catalytic Converter Foam Direct Spray Cleaner, and Engine Flush to address multiple causes of P0420 & P0430 codes.
Enhanced Engine Performance: Restores engine performance, restores fuel efficiency, and ensures proper operation of critical components like the catalyst and oxygen sensor.
Effective Cleaning: Thoroughly removes soot and carbon deposits from the entire exhaust tract (catalytic converter & DPF system).
Engine Flush Cleaner: Sludge Removal: Removes all sludge, residues, and contamination from internal engine surfaces. Boosts Power: Reduces oil and fuel consumption by removing harmful varnish deposits. Extends Engine Lifespan: Neutralizes engine acids and restores engine compression.
PROVEN TO REDUCE EMISSIONS — Government-tested results show HC reduced from 108 to 67 ppm and NOx from 986 to 332 ppm. No other catalytic converter cleaner can show you real test data like this.
FIX P0420 & P0430 CHECK ENGINE CODES — Dissolves carbon deposits from your catalytic converter, O2 sensors, EGR valve, and turbocharger. Clears the most common emissions-related fault codes without expensive shop visits.
PASS YOUR SMOG & EMISSIONS TEST — Formulated with German technology to deep-clean the entire exhaust system. Used by thousands of mechanics and emissions testing facilities across the US.
EASY 40-MINUTE TREATMENT — Simply pour into fuel tank with 5-15 gallons of gas. Drive for 40 minutes and let the formula work. No tools, no mechanic, no removal needed. Works while you drive.
SAFE FOR ALL GAS & HYBRID ENGINES — Compatible with every gasoline and hybrid vehicle. TÜV-certified formula made in Germany. Use every 3,000 miles for preventive maintenance to avoid costly catalytic converter replacement ($1,000-$3,000).
Increase power, performance, mileage and save gas: Cleans by not only the entire emissions and exhaust system, but the fuel system as well. Works with gasoline, ethanol and hybrid vehicles.
Save on expensive fuel system and emission control repairs: Regular use every 5,000 miles tunes-up the fuel, emissions and exhaust systems keeping them clean and preventing the CEL light from returning.
Will not void manufacturer’s new vehicle warranty: Specifically designed and safe to use on vehicles which have oxygen sensors and catalytic converters. Exceeds EPA compliance performance criteria.
Works on all fuel injected, direct injected, carbureted, turbo, GTDI, Ecotec and EcoBoost engines.
DON'T GAMBLE ON AN UNPROVEN BRAND: A leaking engine, head gasket, cooling system, power steering or transmission is your one shot to avoid a bigger repair bill – reach for the brand proven for over 75 years
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.
