Cleaning the air intake and valves

Clean your air intake and valves

Clean your air intake and valves

It is normal that from the first kilometers, carbon deposits accumulate in the air intake and on the valves. Depending on your driving habits, the performance of your engine decreases by increasing consumption and losing power! Cleaning the air intake and the valves is necessary to avoid mechanical problems and failing the technical inspection.

What is the use of the air intake?

The air intake is used to bring air directly to your engine, but it also captures some of the exhaust gases through the EGR valve.

The valves are located on the upper part of the engine, in direct connection with the air intake.

Their role is to open and close according to the engine explosion cycle.

How and why does the air intake get dirty?

When you drive, the burnt gases go out through the exhaust valves and create carbon deposits. The same reaction appears on the intake valves because of the EGR valve. Depending on your driving habits, these deposits can prevent the valves from closing and therefore from sealing.

If the valves are not correctly cleaned, they will lose their tightness and the petrol or diesel engine will lose power.

Why should you clean the air intake?
