Where To Buy
STEP 1

Start by removing these 4 bolts
STEP 2

Next push UP on the red locking tab
(see arrow) to remove the harness to
the MAF sensor
STEP 3

Pus the grayish button and then pull
up to disconnect both lines (see
arrows).
STEP 4

Loosen both screws,
One that connects the rubber
tube to the throttle body and
the other to the factory air
cleaner lid (see arrow)
STEP 5

Loosen the 2 screw on the factory air
cleaner lid (They stay within the lid and
don't come completely out)

Remove the stock filter
STEP 6

Notice the slot on the inside of the  factory air cleaner lid.
This is where  the filters urethane ring will be seated in.
Its a good idea to pre fit the filter here just to see how it
goes and will seal up when you actually install it.


NOTICE : The red arrows simply represent the bottom of
the lid which comes into contact with the filter first when
closing the lid. We will focus on this in step 9  
STEP 7

Install the Attack Blue Filter into the
factory air cleaners housing.
STEP8

After the filter is installed, reattach the
factory air cleaner lid by placing the 2
"male" tabs into the 2 "female" slots.
Sometimes the filters urethane ring
gets a little in the way. Simply wiggle
the lid around & push down to make
sure its all the way down & in.

STEP 9

While keeping the 2 tabs in the slots, slowly
swing  the factory air cleaner lid up to close
and seal.
IMPORTANT, while bringing the lid up to
close, watch & make sure the bottom of the
filters urethane ring is landing into the lids
slot (see white arrows).

Make sure the filters entire urethane ring is
fitting into the lids slot to make a good seal.
STEP 10
Place back, re attach & tighten all
screws & bolts to the proper torque
spec.
