Air silencer removal on a 1999 Ford Escort 2.0 sohc

The lower intake resonator/air silencer is a sound dampening device to quiet the engine sound heard inside the car. The stock intake draws air through a 1.5" hole from inside the driver's side fender. If you remove the resonator that will make it easier for the engine to draw in air, since it will now have two openings once the resonator is removed. Removing this restriction gives a noticeable gain in horsepower. This is how I removed the Air Silencer out of my 2.0 sohc motor as always use common sense when working on cars and use this a guide. Do not hold me responsible for anything that goes wrong.

Tools you will need:

Flathead screwdriver
Pliers
Socket wrench
10 mm socket
12 mm socket
4" extension

First, unscrew the hose clamp holding the air hose coming from the air filter box. Squeeze and separate the wiring harness that attaches to the air filter box. Remove the long, skinny tube from the side of the air filter box by squeezing its hose clamp with pliers. Unlatch the metal band that holds the two halves of the air filter box together. Separate the two air filter box halves. Remove the air filter box half closest to the engine bay.

Unscrew the three, shiny 12 mm bolts holding the other half of the air filter box. Remove the other half of air filter box by slightly twisting and pulling the air tube from its tight rubber molding. You will need to remove the rubber molding that held the air tube as one unit with the 2nd half of the air filter cone. It is held into place by three, 10 mm screws: one holding the A/C tube bracket on, and the other two below. You should be able to see the lower intake resonator more easily now. It has the appearance of a black milk carton.

This is what it looks like out of the car and it is in the same position as it was in the car (circled in the other photo)

Slightly twist the lower intake Resonator to remove it. Thats it, now you just need to put it all back together!

Screw the rubber molding back into place on the driver side fender. Assemble the airfilter box's bottom half by bolting it down again.

Attach air filter and the second half of the air filter box by re latching the clamp. Using pliers, attach the long, skinny tube with the hose clamp. Tightly screw the air tube to the air filter box with the hose clamp. Remember to plug the wiring harness back onto the air filter box.

This is the new hole created that will allow more air to come in (also shown is the rubber molding going into the fender that was mentioned earlier)

This hole used to mate with the resonator. You will have the hole in the fender and now this 2.5" hole which is what will allow more air to come into the throttle body

This is the hole that what was allowing the air into the filter before we changed anything
