Audi 4 Cyl 1.8L Catalytic Converter

About

A catalytic converter is a device that reduces the toxicity of emissions produced by the internal combustion engine. It contains a catalyst that converts harmful vehicle emissions like hydrocarbons and carbon monoxide into less toxic substances such as water vapor and carbon dioxide. Catalytic converters also contribute in controlling air pollution by burning unburned gas in the tail pipe. A damaged catalytic converter will result in poor exhaust emission which is a health hazard. If your car's engine does not run properly over a long period of time, the catalytic converter may become hot or corroded with foreign substances such as oil, causing it to be ineffective. If this should happen, the catalytic converter must be replaced. Auto Parts Network carries high quality automotive parts at low prices. Hide

2000 - 2006 Audi TT Catalytic Converter 4 Cyl 1.8L Magnaflow
- Additional Product Notes and Features:
  • Catalytic Converter Features:
    • Universal catalytic converter
    • Stainless steel casing and tubes
    • Heavy metal catalyst has more concentrated catalytic elements
    • Requires welding, cutting or tube bending to install
    • Complies with all EPA/Federal emissions standards outside California
    • Backed by 25000-mile, Magnaflow warranty
    • Disclaimer: Never install or use this catalytic converter in a state with California emissions standards
  • This Magnaflow Universal catalytic converter covers a wide range of vehicle applications. However, welding, cutting, and tube-bending are often required when installing. They have a ribbed body that reduces expansion and distortion when the converters heat up. The ribs act as a channel that protects the cushioning mat from direct exposure to exhaust gases and hold the ceramic catalyst in proper alignment. These converters use a ceramic-coated, monolithic honeycomb catalyst for maximum flow and surface area.
