This Kit requires that the firewall is drilled.
This kit offers higher levels of rotor sound (whine) within the cabin due to the direct path from the CJ inlet through the firewall.
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.
Cut the insulation along the horizontal line with supplied blade.
Tuck the insulation down in the driver side footwell behind the brake pedal to the left of the steering column. Tuck the insulation up and down behind itself.
Use a center punch to mark the drilling point for the 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) After using the center punch to mark the drill entry point, drill a pilot hole first then using the supplied drill bit at low speed and using windex as lubrication and cooling to avoid (overheating) and damage to the drill bit. Drill on low speed and keep pumping the windex flooding the bit.
Make sure the drill and hole saw is flush with the fire wall sheet metal as not to catch and edge and damage drill bit. Drill all the way through with the bit. See video below for drilling.
Install the supplied wider grooved grommet working into the hole which was cut in the firewall. Use supplied grease on the bare metal edges for protection. Add some grease to the grooves of the grommet to prevent corrosion.
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.
Drilling the inlet pipe in the location between the JET letters as pictured below. Drill with supplied drill bit on the side of the inlet pipe facing the firewall. The inlet pipe should be removed and filter and MAF removed before drilling pipe as not to get any fillings in the inlet path. Clean pipe as needed after drilling. Pipe and filter are remove by taking the driver front wheel off and the wheel well liner, this gives access to the filter which needs to be removed before the CJ inlet can be pulled out.
After rubber Grommet is installed push the 1” hose barb into the grommet from the inside with supplied grease to help seat and seal. SEE VIDEO BELOW
