How often is the intake manifold cleaned?

1. The intake manifold should be cleaned every 20,000 to 30,000 kilometers. Due to various problems such as engine oil quality, a large amount of carbon deposits appear in the intake manifold after the engine works for a period of time. If the intake manifold is not cleaned in time, the situation will become more and more serious, which will affect the engine work, resulting in insufficient power and difficult start.

2. The intake manifold refers to the intake pipe from the back of the carburetor or throttle body to the front of the intake port of the cylinder head. Its function is to distribute the mixture of air and fuel from the carburetor or throttle body to the air intake of each cylinder.

3. The intake manifold must distribute air, fuel mixture or clean air to each cylinder as evenly as possible, so the lengths of gas passages in the intake manifold should be as equal as possible.
