Trucks Of The Month
I searched hours on hours to find an intake
system designed for my 3.0V6. Not finding any made for my year, I
decided to make my own.
The first step in completing any project is to research. I have done the
dirty work and have compiled my findings here to make your life easier!
Now, you must gather all the parts needed.
First, I purchased two civic intake tubes from a local Autozone. Their
website, autozone.com may carry the product also. They only carry one
civic intake tube and it is a universal intake for certain year civics
unknown to me. They come with two black silicone boots, hoses, plugs,
and screw clamps. You will use these for the installation. However, you
will also need to purchase one 3” to 3” silicone boot. I bought a
blue one from summitracing.com.
You will need three metal screw clamps at the least, and six at the most
if you want your intake EXTREMELY secure.
hardest part to fabricate will be the MAF sensor adaptor. If you plan on
using a cone filter like the one pictured above, you will need this
adaptor. Some companies sell these, but I opted to make my own. First, I
bought a shower drain adaptor with a 3” inner diameter. I then made a
template on the bolt side of the sensor. Place the sensor square side
down and trace it on a piece of paper; also remember to trace the holes.
Cut the template out and trace it on the shower drain kit with a marker.
It won’t line up perfectly so you may have to free hand a little bit.
Cut the shower drain pvc with a jig saw or other cutting blade.
You will have to remove the stock air box assembly, but also have the
option of leaving the stock air box base.
Now you must cut the two intakes to fit. Every truck may be close to the
same measurements as mine, but I suggest custom fitment and cutting.
Line up the first (#1) intake and mark it where it is 1-inch from the end
of the alternator. Cut the intake at that mark. Next connect the second
(#2) intake using the blue silicone boot and place your assembled
filter, MAF, and MAF adaptor assembly where it would lie if installed.
Now cut the #2 intake so that you will have room for the filter/sensor
There is only one more pvc piece you will have to make. I made a 45
degree bend using a 90 degree 3-inch inner diameter pvc piece and cut off
the end connections.
Now comes assembly. Disconnect the battery before you begin. This will
allow the computer to reset just in time to get used to the new intake.
connect the 45 degree pvc bend to the manifold using a black silicon
boot and screw clamps. The black silicon boot on the manifold slides
right over the 45 degree pvc piece. Then the 45 degree pvc fits snug
over the first intake tube. You can use a high temp. silicone if you do
not trust your connection. Next connect the #1 and #2 intake tubes using
the 3” to 3” silicone boot and screw clamps. Bolt on the Maf adaptor
to the Maf, and clamp down the cone filter before connecting it to the
#2 intake. Now connect the #2 intake to the Maf sensor assembly using a
black silicone boot and clamps.
Next connect the black hose included with the kit from the passenger’s
side valve cover to the #2 intake. Using the plugs that came with the
kit, plug the unused connection on the #1 tube.
Everything is finished now. Crank up the engine and let her roar! Check
all connections for leaks. If you recognize a stumble or shaking in the
engine that you never had before, then you may have a loose connection.
You should notice a big increase in low and mid range power since the
engine is breathing better. Keep in mind, regular maintenance of your
open element filter is necessary to maintain performance and
