ENG: Cold Air Intake Install

[ACCLUDE91]

This is courtesy of Lightning Motorsports


Start by removing the bolts that secure the intake box and intake vacuum box assembly


Remove the bolt from the rear of the airbox


Remove the (2) vacuum lines, electrical connector, and vacuum box


Remove the lower resonator attachment screw and note the intake tubing to be removed in the next step


Loosen screw-clamp, remove airbox and lower piping


Using pliers, remove clamp on breather hose


Loosen clamp and remove vacuum line


Remove intake hose and pull the breather hose loose from intake; remove intake


Remove vacuum line (previously attached to vacuum box) and detach from throttle body. Cap with supplied vacuum cap.


This is the port to cap off. We also have the vacuum line, disconnected earlier, that we will install the filter-foam into.

[ACCLUDE91]

AEM filter foam - trim a small section to use


Insert filter foam into hose left over from removal of intake tubing.


This is the factory opening to the lower resonator box - it will be enlarged to fit the AEM


Remove panel clip and 10mm bolt from inner fender liner


Remove 10mm bolt from underneath on lower splash panel - pull panel downward


Remove lower fender liner retaining clips. One is not visible in this picture as it is obscured by lower panel - pull back to expose lower resonator


The factory lower resonator should now be visible. Remove rear bolt


Remove front bolt and remove lower resonator assembly.


Cut hole with suitable cutting device (tin snips. hole saw, pneumatic nibbler) You can trim out the hole with a piece of slit vacuum tubing


Install AEM rubber isolator mount

[ACCLUDE91]

Instal lhose clamp and coupler to throttle body; leave loose.


Mount the "ear" on the intake to the rubber soft mount using the washer and nut provided.


Reconnect battery-chassis ground and tighten - Check intake for clearance where it passes through the hole


Tighten hose clamps and install hose to couple the AEM intake to the stock breather pipe.


Tighten clamps on hose assembly.


Slide on air filter, install clamp and tighten;make sure to check for clearance. Replace lower splash shields


This is what it should look like when done.

this is only for a EX accord though. less steps on the others.

i wonder whats the purpose of those vacumn lines that are plugged and that is filtered.

i know one of them goes into a vacumn box but i still dont know why it should serve a purpose. do u think with my stock intake system i can cap off that long vacumn line?

[4drcord]

i think you want to keep it because there is a sensor that opens a valve in the stock air box piping that allows more air flow when needed.this is only avail on the EX. but i guess when you get a cold air you have to remove it.

[accordztech]

i wonder why wouldnt AEM just make a little pipe for that to go in the intake like the stock ex had. (talking about the vacumn line u plug with a foam filter).

I have a Prelude CAI, and it has a small hole on the top of it, near the intake manifold. I just plugged it, since I don't know what was supposed to go in it. Looks like the Accord CAI didn't have that hole...

deveergote:

could it be for a dry nitrous system?

[deevergote]

You know, I never thought of that! That might be a possibility! Of course, I would never want to go dry anyway, but who knows... That might be it's purpose.

[HondaFan81]

yea neither would I, there's always room for alcohol...wait, nevamind

[accordztech]

i been playing with that vacumn line..if u plug it and rev the engine...the engien lacks power in a way...

[92Accord EX-R]

I just spent the last .... too long.... putting this bad boy in. Sounds amazing, and there's a noticable difference. Now if I floor it, torque steer is noticable. Which I like, and will enjoy until the illuminas and neuspeeds get here. I have noticed that my idle is a little bit lower than before the intake... Anyone have any suggestions about raising it slightly? Is it as simple as adjusting the screw on the throttle body?

PS - The hardest part is hacking away at the fender. The weird part is disconnecting vaccuum lines and not re-installing. The best part is the power

[Toddy]

does that air resonator box and sensor need to be unplugged and removed if you use a short ram. i installed mine yesterday and noticed a huge differance in acceleration. also it has a great tone. i unplgged that sensor after reading this and noticed slightly move power and a little louder tone.

[92Accord EX-R]

Not sure. I was under the impression the extra valve in the intake was exclusice to EX / EX-R / SE's... but I found out today that the newer 5th gens all have them.

If you unplugged and capped the vaccuum line at the intake manifold, then yes, you'd need to remove that vaccuum box and line because it's not hooked up to anything.
