Fold the carpet down in the driver side footwell behind the brake pedal to the left of the steering column & secure by inserting a small screw as shown in the image through the carpet.
Pull the retaining clip off the carpet stud to enable the cutting of the insulation.
Use a center punch to mark the drilling point for the 1 3/4” hole. Draw a line across from the steering column bracket point. Draw a second vertical line approximately ¼” from the raised sheet metal contour as shown the image.
To determine the exact point, you will be able to feel (using your fingers) and see the seam.
After using the center punch to mark the drill entry point, drill using the supplied hole saw at low speed and using a light oil for lubrication to avoid (overheating) and damage to the drill bit.
Make sure the drill hole saw is flush with the firewall sheet metal as not to catch and edge and damage drill bit
Locate the “V” like contour in the air box wall as shown in the image, using your fingers.
This can also be seen upon visual inspection.
With the airbox in place, using a tape measure locate a point 4” from the top of the airbox and using a slight angle, drill in the “V” shaped area approx. ¼” to the left side of the wall.
Be sure to check for coolant hose clearance on the other side as to not damage when drilling.
Coolant lines may be routed slightly differently on each application.
It may be necessary to go inside (the footwell area) to pull the hose end through to a depth of about 1 ½ “ using pliers.
Image showing the sound tube inserted through the grommet and firewall hole.
Insert the large grommet (supplied) in the drilled hole in the air box to secure the sound tube.
Use your fingers to pinch the end of the hose while pushing hard to insert the hose into the grommet. Use grease or WD40 on the inside of the grommet and hose end to aid in installation.
This Image shows the position of hose installed and positioned at the rear of the shock tower.
The almost straight position and direct path of the sound tube to the firewall, allows for more sound transfer into the cabin and a greater effect than the stock OEM sound tube.
The installation is now complete.
