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.

R ead and understand these instructions BEFORE attempting to install this product. 1) Getting started a) Make sure vehicle is parked on a level surface. b) Set parking brake. c) Disconnect both battery terminals. d) Jack up front of vehicle, place on properly rated jack stands, remove left, front wheel. Remove fender liner. e) If engine has run within the past two hours let it cool down. 2) Removing the stock air inlet system Upper clamp Breather hose a) Stock intake system. b) Pull breather hose off of valve cover. Loosen the upper and lower hose clamps on the stock inlet tube. c) Unplug the MAF sensor. Remove stock inlet pipe. Release four clamps on the air box and remove upper air box from the vehicle. d) Loosen the four nuts that hold the MAF sensor to the airbox. Carefully set aside the MAF sensor. 2
e) Release air snorkel by first pressing in the centers of the plastic rivets. f) Loosen the three bolts holding down the air box. Remove air box and snorkel from vehicle. g) Remove lower mounting bracket. h) Loosen the three bolts that hold in the lower air box and remove it from the vehicle. 3
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. Size 52 clamp a) Attach MAF adapter to MAF sensor using the supplied bolts and lock nuts. b) Attach rubber reducer to MAF sensor using the size 52 hose clamp. c) Place rubber elbow with two hose clamps onto the throttle body. The longer end attaches to the throttle body. d) Insert upper CAS pipe into rubber elbow. Confirm that the nipple on the pipe is pointing towards the center of the vehicle as shown. 4
e) Install the supplied breather hose as shown. Secure both ends with supplied ¾ hose clamps. f) Attach the bracket on the upper pipe to engine using the supplied 6mm bolt and washer. Place the pipe s tab behind the stock plastic tab. Also attach the MAF sensor to pipe utilizing the rubber adapter as shown. g) Plug wiring harness into MAF sensor and attach lower pipe to MAF sensor using silicone hose and two hose clamps. h) Install rubber mount into frame and attach support bracket as shown. Do not completely tighten the lock nut. See next page for proper installation. 5
Lock Nut Fender Washer Rubber Mount Chassis Inlet Pipe Support Tab i) Proper installation of the rubber mount. j) Install air filter to the lower end of the CAS pipe. Check clearance of the filter and tighten the hose clamp. 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 fender liner. b) Position the pipes so that they do not touch any other surfaces and tighten all hose clamps, then tighten the bracket mount. c) Replace fender liner. d) Replace wheel and torque lug nuts to the proper value. e) Reconnect battery terminals. f) Start engine and perform a final inspection before driving the vehicle.
