The 2002 Nissan Altima is a popular, reliable sedan that has become a common sight on roads across the country. Its impressive performance and durability are largely due to its high-quality catalytic converters. But just how many catalytic converters are in a 2002 Nissan Altima? In this article, we will explore this question in detail, looking at the key components of the vehicle’s exhaust system and what role they play in the overall performance of the car.
How Many Catalytic Converters Are in a 2002 Nissan Altima?
The Nissan Altima was first introduced in 1992, and the 2002 model was the sixth generation of this sedan. Depending on the trim level, a 2002 Nissan Altima can have one or two catalytic converters. The standard engine for a 2002 Altima is a 2.5-liter 4-cylinder, which has only one catalytic converter. A 3-liter V6 engine is available as an upgrade, and it has two catalytic converters – one for each bank of cylinders in the engine.
Both engines meet emissions standards set by the federal government, but having more than one converter helps reduce emissions further by allowing a greater surface area to convert exhaust gases into non-polluting elements. Replacing either type of converter on a 2002 Altima can be relatively expensive due to their location near the bottom of the vehicle and their large size compared to other cars’ converters; however, they are designed to last upwards of 100K miles before needing replacement in normal driving conditions.
