    Looking to purchase Nissan Altima Catalytic Converter with a specific budget in mind? Browse products by price:
    Now that most states enforce strict guidelines on exhaust emissions, it is imperative that you have a high-performance catalytic converter in your exhaust system. Simply, this component ensures that your emissions are as less damaging as they can be to the environment. A Nissan Altima catalytic converter works in conjunction with your engine; the engine must have the right temperature and proper air-fuel mixture in order for the catalytic converter to not clog. Trapped contaminants also render the converter inefficient. Without a good catalytic converter, your exhaust will be billowing out black or white smoke, which is a prelude to a failing score in the emission test.

    FAQ

    Ask APW
    • Answer: A catalytic converter is just one of the components responsible for a vehicle's emission. If the engine is bad and underperforming, or if the wheels lack enough air pressure, the general emission will be affected. Also, contaminants in the converter will affect the part's performance; this is why the clogging of unburnt fuel in the converter must be prevented. If a bad emission is caused by a deteriorated cat, then a new one will certainly improve the quality of the car's emission. A new cat will be able to efficiently convert the by-products of burnt fuel into less toxic substances.
    • Answer: A catalytic converter performs better with quality fuel and excellent vehicle maintenance. Using only lead-free gasoline will definitely lessen contaminant buildup in the cat. Also, installing the cat away from a high-temperature area underneath the car will prevent faster performance deterioration. To make a cat converter last longer when it comes to performance, regular tune-ups of the induction, ignition, and engine systems must be conducted.
    • Answer: There is a specific formula in measuring the efficiency of a catalytic converter, and the variables include the amount of gas coming in and coming out of the converter. Basically, the in level is deducted from the out level, and the difference is divided by the out level and the result is multiplied by 100. Thus, a catalytic converter with an upstream emission of 75 and a downstream of 5 will have an overall efficiency of 93%. The efficiency of a catalytic converter can be determined by getting an emission test at a local testing center accredited by the state.
    • Answer: A Nissan Altima catalytic converter must be replaced as soon as its efficiency falls below 90%. Years of driving actually deteriorates the catalytic converter's efficiency, so it is expected that a replacement is necessary four years from the purchase date of the vehicle. Also, black or white smoke coming out of the tailpipe is a good sign for a cat replacement. The emergence of dirty smoke can be stalled by ensuring that the engine has an adequate air-fuel ratio, the injectors provide excellent fuel atomization, and the engine cylinders provide the same output, among others.
