The "00-04 Nissan Altima Exhaust Manifold with cat Nissan Altima 2.5L Exhaust Manifold" refers to an automotive part designed for Nissan Altima models with 2.5L engines, manufactured between the years 2000 and 2004. Let's break down the components of this description:
00-04 Nissan Altima: This specifies the model years of the Nissan Altima that the part is compatible with. In this case, it's for models from the year 2000 to 2004.
Exhaust Manifold: An exhaust manifold is a part of the engine that collects exhaust gases from multiple cylinders into one pipe. In a typical inline 4-cylinder engine like the 2.5L engine in the Nissan Altima, the manifold will collect exhaust from all four cylinders.
with cat: "Cat" is short for "catalytic converter." This is a device that reduces the toxicity of emissions from an internal combustion engine. When it's mentioned that the exhaust manifold comes with a cat, it means that the manifold and the catalytic converter are integrated into one unit. This can be an advantage as it simplifies installation and may provide a cost benefit compared to purchasing the components separately.
Nissan Altima 2.5L: Indicates that the intended vehicle has a 2.5-liter engine displacement. Engine displacement is generally used to identify the engine size and, by extension, the power output of the engine.
When purchasing an exhaust manifold for a Nissan Altima, it's important to match the part to the correct engine size and model year to ensure proper fitment and performance. The combined unit of the exhaust manifold with the catalytic converter is designed to help reduce emissions and improve the efficiency of the engine. This integrated unit is typically made from materials that can withstand high temperatures and corrosion, such as stainless steel or cast iron.
