Special notes to installer
While we have taken every design precaution to ensure that this product will function correctly on the vehicles listed, it must be made clear that the original converter did not fail due to age or mileage. The factory converter is designed to last the lifetime of the vehicle. It has no moving parts and does not erode or otherwise wear out. The factory converter likely failed due to a fuel management problem or from chemical contamination due to impurities found in some fuels. The converter can only handle certain amounts of unburnt fuel. If the vehicle is running too rich, or if the combustion is not consuming most of the fuel before it enters the exhaust, the converter can be overheated or otherwise damaged. It is for this reason that the vehicle should be properly tuned on a regular basis. O2 sensors should be replaced every 80,000 miles, spark plugs every 60,000 - 100,000 miles, and the injectors and combustion chambers should be cleaned with a product designed for this purpose every 10,000 miles or every year. Use of an incorrect octane fuel may contribute to the formation of deposits in the converter, which can harm the catalyst. Use only the octane recommended in the owners manual. Only OE spec spark plugs and wires should be used, as other brands may cause poor combustion and contribute to deposit formation.

We have determined that failure of either the front O2 sensor (the front wide-band sensor, also known as an Air-Fuel Ratio Sensor) or the rear or downstream sensor, can trigger a false P0420 code. Both sensors should be replaced when you replace the converter.

EPA approved for all Federal and California compliant vehicles, including Low Emission Vehicles* in all states excluding California. Not legal for sale in California. If your vehicle is registered in California, do not purchase this part. If your vehicle meets California requirements, but is not registered in California, this converter will work on your vehicle.
