OEM INFINITI G35 Catalytic Converters

The engine in your INFINITI G35 burns gas to generate the power it runs on. The combustion process produces noxious fumes -- everything from carbon monoxide and hydrocarbons to nitrogen oxides. The car's exhaust system helps remove them safely. This helps protect you, your passengers, and the environment.

However, no exhaust can work without a catalytic converter -- a cat, for short. Located between exhaust manifold and muffler, the cat contains a metal catalyst coating -- more specifically, a combo of platinum, rhodium, and palladium. These "platinum group metals" capture, contain, and convert most pollutants into cleaner gases -- often, simple water vapor and carbon dioxide.

No catalytic converter lasts indefinitely, though. They can go bad from use and age, and at that point, they need replacing. Luckily, there are signs to warn you. They include a slower and less-responsive engine, trouble accelerating, excessive, often black exhaust smoke, and a sulfuric smell, much like rotten eggs. You may also notice excessive heat coming from under your car.

If your G35 model shows such symptoms, you may need to change its cat. Otherwise, when to replace one is uncomplicated -- do it about every 100,000 miles. When you do, however, be sure to buy the genuine article.

Why Buy a Genuine INFINITI Catalytic Converter for G35 vs. Aftermarket?

The brand designs them to fit the car perfectly. You may not get the same compatibility assurance from off-brand catalytic converters.
