2000-2003 Ford Focus ZX3 Short Ram System Installation Instructions
The AEM Short Ram Air Intake System is the result of extensive development on a wide variety of cars. It is the most advanced short pipe air intake system on the market. Each system is specifically engineered for its particular application. All AEM Short Ram Air Intake Systems deliver maximum performance gains through lightweight, all- aluminum, mandrel-bent tubing that is tuned in both length and diameter. The aluminum will not crack in extended use like plastic. The tube length and diameter are matched for each specific engine to give power over a broad RPM range. Unlike plastic systems that use a continually diverging cross-section, we take advantage of the acoustical energy in the inlet duct to promote cylinder filling during the intake valve- opening event. Every intake is coated with a high-gloss, heat-reducing Zirconia based powder coating.
This special blend of powder coating helps reduce heat penetration, which in turn reduces the temperature of the inlet air charge. The cooler inlet air temperature translates to more power during the combustion process because cool air is denser than warm air. The mass air flow to the engine is increased because of the increased airflow and reduced inlet temperature, which translates to more power. 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.
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) Loosen the hose clamps attaching the primary stock intake pipe to the throttle body and the primary stock intake pipe to the mass air flow sensor.
i) Remove the primary stock intake pipe.
b) Disconnect the wiring harness from the mass air flow sensor.
c) Remove the sensor from the stock intake piping using the supplied Torx™ tool and set aside as it will be used in the installation of the AEM intake. Be careful not to damage the mass air flow sensor.
d) Remove the breather hose from the valve cover to the air cleaner housing.
e) Remove the air cleaner housing from the vehicle. This is done by pulling straight up on the housing. There are no bolts holding the housing in.
f) Remove the two plastic hold downs from the secondary intake tube.
g) Remove the secondary intake tube from the engine mount by lifting straight up.
h) Remove the secondary intake tube through the front of the vehicle.
i) Remove the upper portion of the air cleaner housing assembly.
j) Remove the Stock air filter from the lower air cleaner housing assembly
