Congratulations! You have just purchased the finest Air Induction & Filtration system for your car at any price!
The AEM Cold Air System is the result of extensive development on a wide variety of cars. Each system is engineered for the particular application. The AEM Cold Air System differs from all others in several ways. We take the inlet air from outside of the engine compartment where the inlet air is considerably cooler than the hot under hood air. The cooler inlet air temperature translates to more power during the combustion process because cool air is denser than warm air. AEM has conducted extensive inlet air temperature studies and we have seen temperature reductions of up to 50 degrees by pulling air from outside of the engine compartment. The air mass flow to the engine is increased because of the increased airflow and reduced inlet temperature, which translates to more power. The AEM Cold Air Systems are 50 states Street Legal (some model and years still pending) and come with complete instructions for ease of installation.
Our system is constructed of lightweight aluminum and then painted with a zirconia based powder coat for superior heat insulating characteristics. The aluminum will not crack in extended use like plastic and it is actually lighter than plastic. The tube diameter and length are matched for each engine to give power over a broad rpm range. Unlike the plastic systems that use a continually diverging cross section, we take advantage of the acoustical energy in the duct to promote cylinder filling during the intake valve-opening event.

2) Removing the stock air inlet system
a) Stock intake system. b) Release the clip on top of the inlet pipe.
c) Loosen the hose clamp at the air box. d) Remove bolt. Release the breather hose from the valve cover.
e) Loosen the hose clamp at the throttle body. f) Gently pull inlet air temperature (IAT) sensor from the inlet pipe. Do not pull by wires. Remove the upper air box from the vehicle.
3
k) Remove the left fender liner.
g) Remove the battery by first releasing the tie down bolt.
i) Remove the plastic clip that secures the fuse block.
h) Release the two wire clips on the air box.
j) If equipped with a manual transmission, remove the clutch fluid reservoir from the air box. Secure it to the firewall with AEM Part # 20-445 (sold separately). Remove the air box from the vehicle.
l) Release the two wire clamps on the back of the washer fluid bottle.
4
m) Unplug the washer motor. Pull the washer fluid hoseoff of the motor and drain the fluid into a suitable container.
n) Remove the bolt that secures the washer bottle to thefender.
o) Remove the lower bolt near the front of the washer bottle.
q) Remove the washer bottle from the vehicle. Loosen the bolt connecting the bottle to the lower air box.
p) Remove the upper bolt near the front of the washer bottle. This picture was taken through the front grill.
r) Loosen the positive lead on the fuse block. Rotate it as shown. Tighten the lead.

3) Installation of the AEM Cold Air Intake System When installing the Cold Air Intake System, DO NOT completely tighten the hose clamps or mounting tab hardware until instructed to do so later in these instructions.
d) Reinstall the washer bottle without the lower air box. Reattach the washer fluid hose and plug in the washer motor.
a) Install supplied bolt and washer through fender as shown. This picture was taken from inside the fender well.
c) Mark the pipe approximately ½” above and below the hole in the fender. Remove the pipe and apply the adhesive neoprene material as shown.
Mark pipe here,
and here.
b) Install spacer as shown. Install the lower pipe in the engine bay. Center the pipe in the hole in the fender and tighten the nut on the spacer.

f) Attach the rubber mount to the tab near the washer bottle filler neck using the supplied washer and lock nut.
g) Install the hump hose to the throttle body as shown. h) Install the supplied grommet in the hole on the upper pipe. Insert the zip tie into the hole on the upper pipe bracket (use two zip ties if the car has cruise control).
Cruise control only.
e) Install the supplied silicone hose as shown. Orient the hose clamp screws away from the battery tray as shown.
i) Place the upper pipe in the engine bay as shown. j) Secure the throttle/cc cable(s) to the upper pipe with the zip tie(s) installed earlier. Cut off excess material.
7
k) Insert the IAT sensor through the grommet in the upper pipe. Do not push the grommet into the pipe.
l) Install the supplied breather hose between the valve cover and inlet pipe. Secure it with the supplied hose clamps.
m) Check the fitment of the pipes and tighten all hose clamps. Secure the fuse block to the rubber mount with the supplied lock nut and washer.
n) Reinstall the battery. Confirm that the positive lead from the fuse box is on top of the inlet pipe and is not pinched between the battery and the pipe.
o) Install the air filter onto the end of the pipe. p) AEM Cold Air Intake System installed.

4) Reassemble the vehicle
a) Inspect the engine bay for any loose tools and check that all fasteners that were moved or removed are properly tightened, including the wheel and fender liner. Torque lug nuts to 85 lb-ft.
b) Confirm that the air filter does not contact any surface. c) Position the pipes so that they are in line with one another, tighten all bolts or screws and tighten all hose clamps. d) Reconnect battery terminals. e) Start engine and perform a final inspection before driving the vehicle.
5) Service Information and Optional Accessories
a) Service your AEM filter element with AEM's Filter Cleaning System (Part # 21-100) at least every 50,000 miles or 30 months to maintain optimum performance. We recommend that AEM filter elements be serviced every 25,000 miles or 15 months on off-road and high-performance street applications.
b) If your car is equipped with a manual transmission, the clutch fluid reservoir can be properly supported with the AEM Clutch Reservoir Bracket, Part #20-445
c) If you anticipate traveling through water that is deep enough to completely submerge the air filter, this kit can accept an AEM bypass valve (Part # 20-402S).
