Where is the air intake of a sedan located?

The air intake of a sedan is generally located at the front of the engine. Symptoms of a leaking car intake pipe are as follows: 1. Weak engine operation: Since the air entering the engine through cracks in the intake pipe bypasses the air flow sensor, this portion of air dilutes the combustible mixture in the engine cylinders, leading to symptoms of weak engine operation. 2. Increased nitrogen oxide emissions in exhaust: Nitrogen oxides (NOx) in vehicle exhaust are generated in a high-temperature, oxygen-rich environment. An excessively lean combustible mixture further promotes the formation of nitrogen oxides, thereby increasing the emission of vehicle exhaust pollutants.
I remember being curious about where the air intake was when I bought my first car. Later, while repairing it, I discovered it's located at the front under the hood, near the grille. I’ve made it a habit to open the hood and check, and every time I clean the air filter, I can see that entry point. The front placement is designed to allow cool air to smoothly enter the engine cylinders, improving combustion efficiency. If too much dust accumulates, the engine produces extra noise and fuel consumption increases, so regular cleaning is crucial. In regular sedans, the air intake isn’t positioned too high to prevent water splashes during rain from causing damage. My old Honda always had me worried about blockages, but keeping the front well-ventilated has kept its performance stable. A friend’s car once overheated and broke down because they didn’t pay attention to its location—these small details really do affect the driving experience.
