Key features
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).
Complete Exhaust System Cleaner
One 8.45 fl oz bottle cleans your catalytic converter, oxygen sensors, fuel injectors, combustion chamber, and EGR valve. For severely clogged converters, pair with our DPF/Catalytic Foam Cleaner (SKU 8101) for direct spray cleaning.
