Installation
The RFI installation
procedure can be
separated into three
parts: Removing
the Stock Intake,
Preparing the RFI
Intake and Installing
the RFI Intake. The
diagram on the
right shows how the parts of the RFI Cold Air Intake t together
in sequence.
Removing the Stock Intake
1. IMPORTANT: Before beginning installation, disconnect your
battery at the negative terminal.
Failure to disconnect the battery
could result in personal injury and/or
damage to your vehicle.

3. Swap the CCV tube and the brake vacuum tube with the
included silicone hoses.
• Disconnect the stock tubes only when you are ready to
install the silicone hoses. (This is easier than locating the
connection at a later time.)
4. Tighten all of the band clamps after all of the parts
are in place and connected correctly. (Use a at-head
screwdriver.)

Filter Maintenance
The intake system should be cleaned with the Bully Dog RFI
Cleaning Kit at least once every three months; in dusty climates,
the lter should be cleaned more often. Cleaning the intake is a
two part process: cleaning and oiling the lter.
(1) Cleaning the Filter
1. Remove the lter from the RFI enclosure.
Clean the enclosure if necessary.
2. Remove surface dirt (this step can be
avoided if a Bully Dog RFI Prelter has
been installed).
• Lightly tap the lter.
• Use a soft-bristle brush to remove any
loose particles.
3. Spray the cleaner generously over the
lter and let it soak for 10 minutes.
4. Thoroughly rinse the lter.
• Use regular tap water.
• Avoid high-pressure hoses.
• Prevent dirt from entering the lter by rinsing from inside
out or from the clean side to the dirty side.
5. Let the lter air dry.
• Do not use any method to speed up the drying process.
• Using a blow dryer or compressed air can disgure the
lter and allow particles to pass through.
(2) Oiling the Filter
1. Apply a small amount of oil to the soft-bristle brush and
gently spread the oil over the lter. Be sure to apply only
a small amount of force so the lter is not damaged.

2. Continue applying the oil to the lter until the entire lter
is covered in an even amount of oil. Apply enough oil to
make the lter a solid and uniform blue, but do not go
beyond that.
3. Allow the oiled lter to sit 20 minutes. Re-oil any dry spots
that appear. Do not oil the lter excessively. Excessive
oiling can cause damage to intake sensors.
Prelter
The Bully Dog RFI Prelter is a semi-water-
repellent barrier that will keep bugs and
debris out while lengthening the
time between lter cleanings
and reducing the amount of
time you spend cleaning the
lter.
