Intake Manifold And Filter

1. Intake Manifold
Distributes air/air-fuel mixture to engine cylinders, affecting efficiency and power.
By material:
Cast iron: Durable, heat-resistant; for heavy-duty engines.
Aluminum alloy: Lightweight, improves combustion; common in passenger cars.
Composite (plastic/resin): Low-cost, corrosion-resistant; used in compact cars.
By structure:
Single-plane: Optimized for high RPMs, boosts top-end power (racing/performance engines).
Dual-plane: Enhances low-end torque, suits daily-driven vehicles.
2. Air Filter
Cleans air before it enters the engine, preventing wear and maintaining efficiency.
By material:
Paper: Disposable, cost-effective; standard for regular use.
Cotton gauze: Reusable, high airflow; for high-performance vehicles.
Foam: Reusable, excellent for dusty environments (off-road/agricultural use).
By scenario:
Standard: Balances filtration and airflow for road use.
High-performance: Maximizes airflow for boosted horsepower.
Heavy-duty: Reinforced for harsh conditions.
The two work together: the filter ensures clean air, and the manifold distributes it efficiently, optimizing engine performance.
