Have You Fixed the Problem that Caused your OEM Converter to Fail?

Catalytic Converters are designed to last the life of your vehicle – they do not fail on their own. 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

Burned Converter

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

Oil Fouled Converter

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

Dented Converter

Helpful Tools: Oxygen (O2) Sensor Socket / Wrench | Penetrating Oil | Anti-Seize Lubricant | Sanding Block Pad | Fuel System Cleaner
