OEM INFINITI Catalytic Converters

Most vehicles sold in the U.S. since 1975 have been equipped with at least one catalytic converter, and your INFINITI model is no different. Also known as a "cat," the catalytic converter is an essential component in your vehicle's exhaust system. What it does sounds simple: it takes the pollutants produced by the combustion process and transforms them into less harmful compounds. That helps to keep the air that we all breathe cleaner. How it does that is a bit more involved.

How Catalytic Converters Work

The catalytic converter usually sits between the exhaust manifold and the muffler. It features a metallic coating -- usually made of some combination of rhodium, palladium, and platinum -- that collects most of the toxic byproducts created when your engine burns the mixture of air-and-fuel in its combustion chamber.

Nitrogen is trapped in the cat, while oxygen is allowed to pass through. The process consumes hydrocarbons and carbon monoxide, leaving what amounts to little more than water vapors and carbon dioxide. Those are then released through the exhaust pipe and into the atmosphere.

How To Spot A Failing Catalytic Converter

While you can expect your catalytic converter to last up to 10 years, it can eventually go bad. If it does, you'll want to replace yours as soon as possible. Signs of trouble include:

• Weakening acceleration
• Sluggish engine performance
• You detect the distinct odor of rotten eggs
• You hear loud noises when you accelerate
• Excessive heat coming from under your vehicle
• You notice your exhaust emissions are growing darker
