Help with installing air intake

External Since: Jan 14, 2007 Posts: 1

Hey guys,
I am trying to install a carbon fiber intake tube to replace the stock
one in my 1994 Accord (EX, VTEC) coupe. The
new intake has two small protrusions on top for attaching the two
rubber
tubes to the intake. and that's it. The original has, in addition, a
tube-like plastic thing that is attached to the intake from the bottom.

It's a flat plastic tube that goes into a box near the battery.
There
is a small tube or hose that comes out of this box and goes to either
the engine block or another device. What do this box and the hose do?

I am not talking about the factory air filter, but this black box is
connected to the factory pipe. I don't know what this is. Should I just
remove this, or what should I do? If I don't remove it, then the new
pipe won't fit there. So what should I do? I think 1994-1997 Accords
have this black box (I am not talking about the air filter, but this is
a seperate box below the pipe, and behind the battery) connected to the
factory air intake pipe.

that box is the resonator. it helps tune the intake so there are no
flat spots in the intake charge curve.

bottom line rafi, you're not going to get a lot of enthusiasm on this
group for the mod you're proposing. there are a number of potential
problems including decreased engine life with decreased filter
efficiency, and the risk of water ingestion - not good.

if you want bolt-on performance, go for a better header and a more
aggressive cam. after that, look into getting the head ported and going
for higher compression pistons. before any of that though, make sure
all your ignition components are in top condition. iridium plugs and
magnecor plug leads for example won't magically give you more power, but
they will definitely make sure you don't lose any along the way. also
make sure the valve lash is set right, that the timing belt is set and
tensioned correctly, and that the ignition timing is correct. also,
make sure you have that "max power" thing down. not sure what your vtec
crossover rpm's are on your motor, but the max power for your motor is
way up there near the red line - hondas have no torque, so they won't
"grunt" you off the green light, but with the motor spinning fast
enough, they perform quite decently.
