Installation for 2001-2003 Acura 3.2CL Cold Air System:
1) Getting started
a) Make sure vehicle is parked on a level surface.
b) Set parking brake.
c) Disconnect negative battery terminal.
d) If engine has run within the past two hours let it cool down.

2) Removing the stock air inlet system
a) Remove the stock air box assembly and attaching hardware from inside the fender well.
b) Disconnect the breather hose and the Fuel Injection Air Control System hose from the air inlet tube.
c) Loosen and remove the air inlet tube from the throttle body.
d) Jack the front of the vehicle and support using properly rated jack stands.
i) Remove the lower front splashguard.
ii) Remove the front left tire and remove the inside splashguard (inner fender liner).
e) Remove the resonator from underneath the vehicle.

3) Installing the cold air system
a) Install the 2” long connector hose on the throttle body end of the primary pipe. That is the end closest to the breather nipple.
i) Accord – Install the 2.50” hose clamp on the connector hose and loosely tighten. Install a 2.75” hose clamp onto the other end of the connector hose. 3.2CL/TL – Install the 2.75” hose clamp on the connector hose and loosely tighten. Install a 2.75” hose clamp onto the other end of the connector hose.
b) Install the pipe onto the throttle body.
i) The support tab on the inlet pipe will line up with a threaded hole on the inner fender well. Install the rubber isolator mount and attach the air inlet tube onto the rubber mount. Install the large fender washer and the lock nut onto the isolator mount stud and snug it down. Failure to install the rubber mount will void all warranties of the Cold Air System. Below is a diagram of how the rubber mount should be installed.
c) Install another connector hose onto the other end of the inlet pipe. Gently tighten two hose clamps around this connector hose.
d) Install the secondary inlet pipe through the hole that was left exposed upon removal of the O.E. resonator. Slide the end of the pipe into the connector hose and gently tighten the hose clamps.
i) The support tab on the lower inlet pipe should be aligned with a hole on the lower inner fender well just below the headlight. On some vehicles there will be a plastic wire loom using this hole, if so remove it. Install the second rubber isolator mount through this hole. Use a large fender washer and a lock nut to secure it to the vehicles body. Attach the support tab to the isolator mount stud using another large fender washer and locking nut. Failure to install the rubber mount will void all warranties of the Cold Air System. Refer to the diagram above for proper installation of the rubber isolator mount.
e) Install the AEM filter on to 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.
