If you want to get the best performance out of your car, consider replacing your intake valve. It is best to install stainless steel valves in your car because they will increase performance to your engine and reduce the corrosion that your vehicle suffers. Taking out the intake valves completely is another option. This can allow you to get more power out of your engine.

Step 1 - Locate the Old Intake Valve

Turn the engine off, and allow the car to cool for about half an hour. This will ensure that all of the parts inside the engine are cool to touch. Be very careful and be sure that your car has cooled down because if you do not allow the car to cool down, you could seriously burn yourself. You should then turn your steering wheel to the left because this will allow you to locate the wheel closet. This is where the intake valve is located.

Step 2 - Remove the Old Intake Valve

Once you have located the intake box, remove the metal clips that secure it to the wheel closet. Take off the top of the box, and remove the filter that is located below it. Next, locate where the hose runs into the engine and follow the hose from the intake valve to the engine. Remove the attachments and take off the intake valve using your wrench. Remove any wires by taking out the clips. Guide the air intake hose up to the top of the air box.

Step 3- Prepare the Air Intake Valve

Make sure that your new air intake valve is clean and free from dust or debris. Cover the new valve with a putty called anti-seize compound. This will help the valve continue to work and stop it from seizing up during the cold weather or when it is under stress. It also helps to inhibit the growth of corrosion. This joint compound will help your air intake valve last longer and you will have fewer repair costs.

Step 4 - Install the Air Intake Valve

Push the new valve to the end of the hose. Push it into the space where the air hose connects to the engine and tighten it using the wrench. You should then reconnect the wires, tightening them into the valve using a screwdriver. Push the clips in until they fit tightly on the valve. Replace the air filter into the box, and then close the box. Tighten the screws to make sure that it is firmly fitted.

Lastly, run the engine for a while to make sure that air is being properly taken into the car. If you hear a strange noise, repeat all of the steps to be sure that everything is properly secured.
