1996-2000 Honda Civic w/ B18C1 Hybrid System Intake Installation Instructions
The AEM Hybrid Intake System is the result of extensive development on a wide variety of hybrid cars. Each system is engineered for the particular application. The AEM Hybrid Intake System differs from all others in several ways. 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 Hybrid Intake Systems 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.
Getting Started
a) Make sure vehicle is parked on a level surface.
b) Set parking brake.
c) Jack the front of the vehicle and support with properly rated jack stands.
d) Disconnect battery terminals.
e) If engine has run within the past two hours let it cool down.
f) Remove your current air intake system.
Installing the AEM Hybrid Intake System
a) When installing the AEM intake, DO NOT completely tighten the hose clamps or the mounting tab hardware until instructed to do so later in these instructions.
b) Disconnect the water bypass hose from the bottom of the throttle body. Install with the new 5/16” hose and clamp from the AEM kit.
c) Remove the other end of the water bypass hose from the fitting on the engine. Install the other end of the 5/16” hose on to this fitting and secure both ends in place with ¾” hose clamps. Replace any coolant that was drained out.
d) Attach the reducer coupler. Secure the 2.75” end to the throttle body with provided hose clamps.
e) Check for clearance from the fuel rail to the fuel filter. The fuel line must not rub against the inlet pipe.
