Focus, Escort, Mustang; Ford cars Joe has broken and rebuilt in that order. It is an enjoyable never-ending learning cycle . . . sometimes.
Installing a new air intake in your vehicle is one of the first modifications most people do. It is one of the easiest and cheapest mods you can do and improves the performance of your vehicle. In the next ten steps I will walk you through the process of how you can do it all by yourself in the comfort of your own driveway.
1. Remove Intake and Sensors
Remove your factory intake, MAF (mass air flow) sensor and IAT (intake air temperature) sensor from your vehicle. Both sensor housings will need to be reused in the new intake assembly. Be sure to carefully remove both sensors as they can be very delicate at times.
2. Disconnect Air Hose and Remove Ring Clamp
Disconnect the air hose that is connected close to the throttle body. (Note: some models may have another sensor. Disconnect that as well.) Once this is done, you can now go ahead and remove the ring clamp that connects your stock intake to the throttle body using a flat head screw driver.
3. Remove Rubber Mounts
Next you will need to remove one bolt on the fender using an 8mm socket.
Once removed, you will find two rubber mounts on the bottom part of your stock housing. Make sure to save them as you will need them later on.
Also save the rubber mount from the fender as you will be needing it later on as well.
4. Open MAF Housing Tabs
Using a flat head screwdriver, open the mass air flow housing tabs. Make sure not to damage the mass air flow sensor as it is very delicate and can be expensive to replace.
5. Remove the Mass Air Flow Sensor
Remove the mass air flow sensor wire harness from the old housing using your fingers. Grab the rubber grommet and wiggle it around until you push it through to the other side. It should be simple, however, if you have some difficulty you can always use a flat head screwdriver but be extremely careful. .

Once that is done, you can remove the mass air flow sensor completely from the stock housing using a 10mm socket.
6. Connect the Mass Airflow Sensor to the New Intake
Install the mass air flow sensor on the new air intake piping, matching each end to its respective side. Use the four bolts and gasket mounting hardware that have been supplied with the new air intake to attach everything together.
7. Attach the Air Filter and Bolt the Heat Shield in Place
Using that same piping that has your mass air flow sensor attached, slide it through the heat shield and using the ring clamp provided with the new intake, attach the air filter to it. Make sure that it is secured tightly so that it will not slide off at any point while driving.
Next, slide the air filter into the fender well and using the rubber mount that you removed in step 3, bolt the heat shield in its place securing it tightly.
Simultaneously, you will need to align the bottom part of the heat shield with the two holes on the chassis. Secure them using the two bottom rubber mounts that you removed in step 3.
8. Connect the Mass Airflow Sensor and the Throttle Body to the New Intake
Using the rubber couplets provided with your intake kit, attach the mass air flow sensor to the rest of your intake piping and secure it with the ring clamps provided with your intake kit. Depending on how many clamps you were given, you can use one or two for peace of mind.
Next, use the remaining couplet to connect your intake to your throttle body. You may need to use force with this step as it will be a tight fit so don't be scared. Once that is done, use the remaining ring clamp to secure your air intake to the throttle body.
9. Connect Everything Back up
Once your final assembly is done and looks like the image above, make sure to reconnect everything you disconnected. i. e. mass air flow sensor and air vent hose from step 1. Also make sure that all your ring clamps are tightened securely, as well as every bolt you used throughout the installation process.
10. Do a Test Drive
Now all that is left to do is to start the car and go on a test drive, making sure that there are no issues with the vehicle, such as a check engine light coming on, or possibly rattling from the air intake not being secured properly.
