Chevy Impala,Monte Carlo Direct Fit Three-way Catalytic Converter
How Do Three-way Catalytic Converters Work?
A three-way catalytic converter has three simultaneous tasks:
Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2
Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2
Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [(3x+1)/2]O2 → xCO2 + (x+1)H2O.

OVERHEATED / MELTED
Often caused by unburned fuel entering the converter from a faulty:
Often caused by exposure to emissions substances from:
Leaky Cylinder Head Gasket
Improper Fuel (E85, Diesel)
Worn Piston Ring / Valve Seal
Often caused by road debris, corrosion or other conditions such as:
Air Gap Pipe Failure
Flex Pipe Failure
Stripped O2 Sensor Threads
Material Selection and Manufacturing Process
Sturdy and Durable
All T409 stainless steel raw materials are rigorously tested to work at high temperatures as well as to effectively prevent rusting.
High Flow Cat
Fully filling the honeycomb and covering more metal Pt/Pd/Rh per unit area can effectively improve the conversion rate.
Fully automated manufacturing, machine cutting, machine bending, machine welding etc. effectively reducing human error, ensuring compatibility and quality at the same time.
Breathe Freely and Healthily
Engineered to meet your vehicle’s specific emissions requirements, never worry about P0420 or P0430 code and keep check engine light off.
