Installation Manual

h. Install the air filter.

i. Install the AEM

air filter onto the end of the inlet tube. Push the filter on around 2 inches over the inlet

pipe and install one hose clamp to secure the filter on to the inlet pipe. Once fitment is checked, you

can either push the filter on to the inlet pipe more or less depending on clearances. Tighten the hose

clamp after this is done. Be sure to leave ample clearance between the filter and any surrounding

components.

i. Connect the breather hose between the valve cover and the inlet pipe using the breather hose and two

clamps supplied with the kit. Connect the new supplied water bypass hose and clamps to the throttle body

or the fast idle thermo valve, where equipped, and either the intake manifold or the water outlet neck

disconnected earlier.

NOTE: Replace any coolant recovered during hose removal by replenishing the recovery tank.

j. If your O.E. PCV breather pipe lines up with a grommet then slide the pipe into the grommet. If your O.E.

PCV breather pipe lines up with a nipple then install the 2” long breather hose included in the kit, and

secure it with the hose clamps supplied in the kit.

NOTE: Some 1992-2001 Honda Preludes have an intake air resonator valve located within the O.E.

resonator box. Since this part of the O.E. air intake system is not being reused upon the installation of the

AEM

intake system, the vacuum line running from it to the intake manifold must be removed and plugged

using the vacuum cap included. Simply follow the vacuum line from the resonator box to the intake

manifold. Disconnect the vacuum line from the intake manifold and then install the rubber plug.

4. Reassemble Vehicle

a. Position the inlet pipes for the best fitment. Be sure that the pipes or any other components do not contact

any part of the vehicle. Tighten the rubber mount, all bolts, and hose clamps.

i. Be sure that the rubber mount is not stressed in any way that may lead to premature failure.

b. Check for proper hood clearance. Re-adjust pipes if necessary and re-tighten them.

c. Inspect the engine bay for any loose tools and check that all fasteners that were moved or removed are

properly tightened.

d. Reconnect negative battery terminals and start engine. Let the vehicle idle for 3 minutes. Perform a final

inspection before driving the vehicle.

5. CARB Sticker Placement

a. The C.A.R.B. exemption sticker, (attached), must be visible under the hood so that an emissions

inspector can see it when the vehicle is required to be tested for emissions. California requires testing

every two years, other states may vary.
