Cleaning of intake manifold is an important cleaning task in car maintenance. For vehicles with high mileage and carbon deposits, especially for those with gasoline direct-injection engine, such cleaning is imperative and effective.

When should an intake manifold be cleaned?

Unstable engine in idle status: If the engine shakes, stalls, or is unstable in idle status, there may be carbon deposits that have affected the air flow sensor or fuel injection amount.

Decreased power: The vehicle power is insufficient and the acceleration response becomes slower.

Increased fuel consumption: Insufficient combustion causes higher fuel consumption.

The engine warning indicator lights up: This can occur particularly when there is a fault code in the air-fuel ratio sensor or fuel injection system.

Obvious carbon deposits: There are obvious oil sludge or carbon deposits in the intake manifold.

Excessive emissions: Vehicle exhaust emissions fail to meet standards.

Is it necessary to clean an intake manifold frequently?

The intake manifold does not require frequent cleaning, but it should be preferably inspected and cleaned after a certain period of operation or mileage (such as after 100,000 kilometers or when the vehicle exhibits relevant symptoms).

Regular maintenance: Replacing the air filter can reduce the amount of carbon deposits.

Advantages of vika intake manifolds:

The vika intake manifolds are made of imported material BASF PA66-GF30 through injection molding, which makes the product more durable.

The vika intake manifolds are welded using imported EMERSON welding machine from the USA. The dimensional tolerance can reach as low as 0.02 mm, leading to good dimensional stability and more elegant appearance.

The middle shaft of the flap of vika intake manifolds is made of stainless steel, leading to higher wear resistance and a longer service life.

The vika intake manifolds feature superior strength and good sealing, The swing axle control valve contributes to higher stability.
