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
