PERFORMANCE AIR FILTER INSTALL
Written by Mustangworld.
of pics, I hope your on the net at 28.8 or faster.
K & N Air filter
and cleaning kit . Filter $45,
Cleaning Kit $10. This is what comes in the box.
so you want a little extra HP for under $60 ? Purchase a K & N Air
Filter ! There are other performance filter manufacturers out there all
using the same basic principle to improve air flow...using cotton instead
of paper for air filtration. But remember, cotton alone will not work,
you also need a slight "film" of oil on the cotton to ensure the cotton
grabs all the dirt and grime. This oil gives the cotton a reddish / orange
look. Don't expect to "feel" a great increase in HP. Expect a stang that
sounds a bit louder at high rpms, revs up and down a little faster, has
a little more pickup coming out of turns and breathes easier. The HP gain
depends on your mods, but on a stock stang, I'd say from 2 - 4 HP.
reason to buy a cotton filter is the ability to wash them and re-use them.
Some of us here live on dirt roads and we have to drive several miles
on dirt to get to our houses in the hills (this is where we also "rally
race" our stangs, like a bunch of Pikes Peak racers) the air filters get
real dirty, real quick. Without a K & N Air filter, we'd have to buy
2 filters a year just to maintain a clean intake. A cotton filter can
be washed and re-washed to work like new, for the life of your stang.
can also purchase the K & N "Filter Charger" system for $89. This
is a system (includes a metal bracket and air filter) that completely
replaces your air box and runs the filter element completely exposed
to maximize air intake. Some may say: "hey, that means that you are sucking
in hot air from under your hood!" True, but a completely open element
means better flow, cooler air means slightly better combustion because
the air is more dense, but hot air burns efficiently in a normally aspirated
4.6L as well. A sensor reads the air temperature for best combustion.
Cooler air still enters through the hole the air silencer took up and
from the entire bottom of the engine. The only time the cool air factor
comes into play (in this case) is on cold winter days anyway, if it's
hot outside, it will be hot under the hood, you'll need an intercooler
(aftercooler or air to water cooler) to really make any difference in
performance if air intake temperature is of any concern to you. Keep in
mind that in some situations, an open air element may get dirty faster
than one that is inside a filter box. We just went with the regular $45
air filter element alone, a stock air filter replacement, because this
project stang will see dirt road action almost every day. We left our
stock air box in place, but still removed the air silencer.
right part no. for your Stang. This particular application was: 1996 Mustang
4.6L V8 K & N Filter Part E-0945. Cleaning kit 99-5000.
HERE WE GO!
Here's the 4.6L
Air filter box. We've already removed the air
silencer, so replacing the air filter is a piece of cake. With
the air silencer in place, it's more difficult because the air silencer
goes into the fender well about 10" or so. We only have to remove
one bolt and a latch, I'm touching both with my hand.
What we'll do
is undo the bolt that is holding the top of the box in place.
The bolt comes completely out. When you put this bolt
back, careful not to over tighten it.
Next we'll undo
the big latch that holds the filter box onto the MAS assembly.
This latch is attached to (and comes out with) the air
Now, we just
lift up on the whole thing and pop the whole box (with latch) out forward.
You can see the stock paper element inside. Looks like
a 747 Jet engine intake ! Notice one of the rubber grommet
holes at the bottom of the fender well. Their are two. You'll
need to lay the box down back into these two holes when you
put it back.
Now just pop
off the air box. Your filter may stick to the MAS assembly
like ours did. As you can see, the big metal latch came
off with the air box. Notice the two rubber grommets on
the air filter box. Now is a good time to clean out the
air box with a damp rag.
Clean off the
air filter box with a damp rag. You can also hose it down if
it's real dirty. Dry it off before re-installing, you don't want
the latch to rust. The new K & N comes pre-oiled from the factory
so all we have to do is pop it in!
lift the MAS assembly and fit the new filter over the extruded
center tube. It won't be a perfect fit. The K & N element's
hole is slightly larger than the tube, so you will have to hold
the filter in place while you put the air box back on. You can
see how dirty the stock element was with only 2 months of "off road"
dirt road driving.
While holding the air
filter in place, put the air box back on. Check for
a perfect fit and rotate the box into it's final position,
then clamp the latch down. Now put the whole air box back down into
place, securing the two rubber grommets at the bottom. Last,
bolt the box into place with the one bolt we removed
The kit comes
with a sticker that says "STOP YOU FOOL ! Don't throw away
my air filter, I can re-use it !" It's wise to stick it
some place visible. We put ours on the metal space to the left of
the radiator, just next to the hood support on the passenger
side. Stickers don't stick to well to the air box itself. This is
in case you take your Stang in for service, you don't want
the dudes to trash your filter.
This is the $10
Cleaning kit that you use to clean out your filter. When it gets
dirty, you spray it down with this cleaner, soak it for 15 minutes,
hose it down, dry it, then re-oil it with this oil. Your back
in business. Every K & N filter comes with a million mile
warranty. You can wash your filter like 10 times with this kit.
totally done dede!....til next time.... see ya on the street !
