The Nissan Altima is designed to have a desirable blend of space, economy, and performance. Nissan has been known to pay particular attention to emissions, and they were the first automobile manufacturer to mass produce a vehicle that won the EPA’s zero emissions designation. The key to keeping emissions low is having the car in tune, which converts more of the petroleum into energy and reduces the amount that is converted into wasteful and polluting byproducts.

The Nissan Altima’s catalytic converter takes care of what is left over. Constructed primarily of precious metals of the platinum group, the cat converts the three main harmful byproducts of the combustion process into other, harmless gasses and particulates.

The three main pollutants produced by gasoline engines are carbon monoxide, nitrous oxide, and various hydrocarbons. Nissan Altima catalytic converters can be restrictive, because they attempt to remove every last trace of the harmful emissions. Some cats contain more of the precious metals, which allows a more efficient reaction, which in turn allows the exhaust to flow more freely, increasing the amount of available power. Of course, these catalytic converters are more expensive than the OEM systems. While all states have requirements for vehicles to have functioning and sealed catalytic converters, the regulations in some states are more stringent than in others. The most restrictive regulations are found in California, so when ordering a replacement Nissan Altima catalytic converter, be certain that you are in compliance with your states environmental requirements.Order your replacement OEM or performance Nissan Altima catalytic converter from our convenient online catalogue, and have it shipped directly to your door.
