Show original supplier description
The AEM Induction 21-401P Cold Air Intake System is crafted from polished aluminum and is engineered to significantly improve your engine's airflow. By replacing the restrictive factory air filter and intake housing, this system allows for a greater volume of cooler air to enter the engine. This intake system was meticulously designed, tuned, and dyno-tested by AEM to ensure optimal performance for specific vehicle applications. The system draws in cooler ambient air from outside the engine compartment, which is considerably more efficient than the hotter air found under the hood, further contributing to performance gains. The polished aluminum construction not only adds a custom look but also ensures durability. This AEM Cold Air Intake system is compatible with a range of Honda Civic and Del Sol models. Specifically, it fits the 1992-1995 Honda Civic, including DX, LX, EX, and SI trims, as well as the 1993-1997 Honda Civic del Sol, including S and SI trims. Ensure your vehicle falls within these specific year, make, model, and submodel ranges for proper fitment. Installation involves replacing stock components and requires securing various parts, including an air filter and intake tube, with provided hardware and hose clamps. The documentation advises not to fully tighten clamps until instructed, and some applications may utilize an inlet adapter.
