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.

Read 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 and remove key from ignition cylinder. c) Disconnect both battery terminals. d) If engine has run within the past two hours let it cool down. e) Jack up front of the vehicle and place on properly rated jack stands. f) Remove driver s side fender liner. 2) Removing the stock air inlet system a) Stock intake system. b) Free differential breather hose from inlet tube, if equipped. Use a supplied zip tie to secure the hose to the brake booster tube. c) Pull the crankcase breather hose from the valve cover. d) Loosen the two hose clamps on the ends of the inlet pipe. Remove the inlet pipe from the vehicle. 2
e) Free the clips that secure the mass air flow (MAF) sensor wiring harness. Unplug the MAF sensor. f) Remove the upper air box after first removing the bolt. g) Loosen the screws that secure the MAF sensor. Carefully remove the MAF sensor. h) From inside the fender well, remove the two bolts that secure the lower air box and remove the box from the vehicle. i) Unclip the two wiring harness connectors and move them two places lower. 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. a) Utilizing the stock screws, install the MAF sensor into the AEM CAS pipe. b) Slide the silicone coupler and supplied hose clamps over the throttle body. c) Install the rubber mount in the upper hole used to secure the lower air box. d) Install the rubber edge trim onto the metal lip behind the headlight. e) Place the inlet pipe in the engine bay. 4 f) Place the large washer over the mounting tab. Lightly thread the lock nut over the washer.
Rubber Mount Chassis Locknut Washer Inlet Pipe Support Tab g) Proper rubber mount installation. h) Place the air filter over the end of the inlet pipe. Tighten the air filter hose clamp. i) Attach the tree mount zip tie to the MAF sensor wiring harness. Trim the excess zip tie band. j) Plug the tree mount zip tie into the nipple near the MAF sensor. Plug in the MAF sensor. k) Secure one end of the supplied breather hose onto the valve cover with the supplied hose clamp. 5 l) Secure the other end of the breather hose to the inlet pipe with the supplied hose clamp. Zip tie the hose to the fuel line.
m) AEM Cold Air Intake System installed. 4) Reassemble the vehicle a) Reinstall the fender liner. b) Inspect the engine bay for any loose tools and check that all fasteners that were moved or removed are properly tightened. c) Confirm that the air filter does not contact any surface. d) Position the pipe so that it does not touch any surface, tighten all bolts, nuts or screws and tighten all hose clamps. e) Reconnect battery terminals. f) 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. b) If you anticipate traveling through water that is deep enough to completely submerge the air filter, replace the AEM Cold Air System with the stock intake system.
