Universal Direct Fit Three-way Catalytic Converter

How Do Three-way Catalytic Converters Work?

A three-way catalytic converter has three simultaneous tasks:

1. Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2
2. Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2
3. Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [(3x+1)/2]O2 → xCO2 + (x+1)H2O.

Nilight's Direct Fit Converters are engineered to meet your vehicle’s specific emissions requirements and most Come With the Replacement Gaskets at NO Additional Cost!

Catalytic Converters are designed to last the life of your vehicle. It is important to fix the source of the problem before replacing your OEM converter. There are three major reasons a converter fails.

OVERHEATED / MELTED

Often caused by unburned fuel entering the converter from a faulty:

• Spark Plug
• Exhaust Valve
• Oxygen Sensor
• Fuel Injector

CATALYST POISONING

Often caused by exposure to emissions substances from:

• Leaky Cylinder Head Gasket
• Silicone-Based Sealant
• Improper Fuel (E85, Diesel)
• Worn Piston Ring / Valve Seal

STRUCTURAL DAMAGE

Often caused by road debris, corrosion or other conditions such as:

• Air Gap Pipe Failure
• Flex Pipe Failure
• Stripped O2 Sensor Threads
• Broken Hangers

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.

Direct-Fit

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.
