Painting Car Intake Manifold – Full Guide

Intake manifold is an essential part of the engine. It is primarily responsible for supplying the air and fuel mixture to all engine parts.

Therefore, without a manifold, the engine cannot function properly. It holds the real power and ignition system of your vehicle.

Thus, most people want to glorify it by adding specific artworks and colors.

Painting car intake manifold does not cause any extensive trouble as it is optimal. A painted manifold looks quite appealing whenever you remove the car hood.

So, by adding these adornments, you can attract buyers or grant a personalized touch to your vehicle.

The Necessity Of Painting Car Intake Manifolds

There are several reasons for painting car intake manifold. It adorns the manifold as well as keeps it safe.

Over time your car machinery is likely to become a corrosion victim. Metals are pretty susceptible to this phenomenon.

Therefore, you must take specific measures to ensure that engine parts remain in pristine condition.

Most paints are temperature resistant, so the intense heat buildup in the engine does not impact them.

These paint coatings protect the manifold from becoming exposed to the oxides in air and oil.

Step-By-Step Process

Following are the steps you should follow for separating the structure and painting the car intake manifold.

Throttle Body

The throttle body is adjacent to the intake manifold and assists the fuel intake and supply by the manifold.

However, if you are painting the car intake manifold, you will have to remove it. It is mechanically attached to the manifold through bolts.

Therefore, you need to assess the attachment sites and the particular tools. The analysis allows you to remove them without getting too baffled efficiently.

The throttle body also has coolant hoses, electric plugs, and four to five bolts that keep its structure intact.

To remove the electrical plugs, you need to detach the particular components that hold these plugs.

After removing those, you get clear access to all the plugs and take out all the plugs and wires.

Afterward, you should remove the hoses. Any needle-like tool can help take off these coolant hoses as they have a clamp-like structure that keeps them in place.

In front of the manifold, the four bolts are present. These are the primary source of attachment between the two systems.

These are tightly bound, and therefore, you will need some effort to loosen them.

Turbo Inlet Tubes

If you have a turbo vehicle, then the network of these tubes will be present. The tube junction has the initiation point behind the manifold.

It is necessary to remove these as they obscure the structure and impede the steps of painting the car intake manifold.

There is a small inlet that attaches to these tubes. You can use any need like clamper to remove the tube from that starting point.

These inlets also have sensors attached to them. To completely take off the pipes, you will need to loosen the grip of these sensors to the manifold.

As the pipe network ends, you will find the turbo inlet on the manifold. It is secured with specific bolts that you can only remove with the help of some particular tools.

Therefore, you will have to assess the bolt type to find the detaching equipment.

It is a complex network; consequently, you must ensure that you efficiently detach all the nuts that join the pipes with the manifold.

Furthermore, do not disassemble the entire pipe network as you will have to place them back after painting the car intake manifold. Only remove it from the manifold.

Keep the sensors attached to the network and do not detangle the pipes from each other.

In such a way, you will not lose track of the association between different parts when placing them back together.

Fuel Lines

Below the manifold, you will notice the fuel lines intricately bound to it. A few 12mm bolts in this region are securing the loans with the manifold.

Use a spanner to loosen the grip and then remove the bolts. You can access the fuel line network as you take out the bolts.

You can pull the entire system out and keep it on the side.

There are no additional attachments; therefore, these lines are easier to remove while dismantling the structure for painting the car manifold.

Fuel Rails

For painting the car intake manifold, you will have to move to the next step, which involves the removal of the fuel rails.

These also have bolts; therefore, you need to scrutinize the entire region to find them. Afterward, you can take these bolts out to separate the fuel rails.

Cleaning The Manifold

After you take the manifold out of the engine, you will notice a significant amount of dust accumulated on it.

The reason is that most car washing services focus on the exterior only, and engine cleaning mainly involves oil change.

Furthermore, if you have an older car model, it has a considerable measure of debris and dirt piled up. It can hamper the process of painting the car intake manifold.

Therefore, you should ensure that you thoroughly clean the manifold before performing any other task.

Any intermediate layer should not be present if you ensure that the paint successfully sticks to the manifold.

When the manifold surface is clean, the color will efficiently stay on. There are several ways to wipe the dust off the manifold.

It would help if you got a clean cloth, sandpaper, or range sponge to remove the debris.

When you do, ensure that you are wearing a mask because the dust gathered on these regions can aggravate your allergies or even cause infections.

Moreover, you can also wear gloves to prevent contact with microorganisms or fungal molds.

Thoroughly scrub off the dust across the manifold and reach the curved regions and corners where most dust is usually collected.

Afterward, you can use acetone to ensure no grease or dirt is left on the manifold. These measures will make the process of painting the car intake manifold effective.

Painting The Car Intake Manifold

To paint the manifold, you have to carefully analyze the structures you want to paint and rule out those that you do not intend to include in the process.

The intake manifold openings and the regions where the throttle body bolts attach are the ones people usually opt to keep out.

Therefore, you can tape such areas to prevent contact with the paint.

Aerosol spray paints are generally preferable for painting the car intake manifold. These should be heat resistant and contain the manufacturer’s instructions.

These allow you to set the appropriate conditions for painting the car intake manifold.

You can spray the paint on the entire manifold surface and let it dry. As soon as the paint dries, you can try another coating to enhance the color of the manifold.

Afterward, let the second coat dry before assembling the throttle body, turbo inlets, and fuel rails.


Painting the car intake manifold is a simple task if you follow the correct procedure.

For sticking the paint to the manifold, it is necessary to follow the manufacturer’s guide on the spray bottle.

Do not dismantle all the structures attached to the manifold. Ensure that you only remove them from it for painting the car intake manifold.

Once you get the manifold, you can experiment with different colors and make it aesthetically pleasing.
