AEM Cold Air Intake Syst em

The AEM Cold Air Intake System (Model 21-430P) is a direct-fit performance air induction kit engineered for 1995–1999 Mitsubishi Eclipse with 4-cylinder engines. This polished aluminum intake replaces the restrictive factory air box with a tuned induction pathway that draws cooler, denser air from outside the engine bay, resulting in measurable gains in combustion efficiency and throttle response during acceleration and sustained driving conditions.

The system features a reusable dry filter element—eliminating the need for repeated oil treatments required by other aftermarket designs. The polished aluminum tube and fittings provide corrosion resistance and maintain consistent airflow geometry without the deterioration common in painted or powder-coated alternatives. Installation uses original mounting points and factory bracket locations, ensuring a clean fitment that doesn't compromise underhood clearance or interfere with other engine bay components. The complete kit includes all necessary hardware and gaskets for a straightforward bolt-on installation.

The Eclipse platform benefits from improved volumetric efficiency at mid to high RPM, where stock induction tuning becomes a limiting factor. Users upgrading to an AEM cold air intake system typically pair it with ECU tuning or fuel system modifications to fully realize performance gains. The reusable filter design reduces long-term ownership costs compared to disposable alternatives and supports both street and track applications where reliable, repeatable air delivery matters.

AEM Induction has established itself as an OEM supplier to major manufacturers and is recognized for precision manifold and induction design. The 21-430P is a purpose-built solution for the DSM platform (Diamond-Star Motors) and delivers the engineering depth expected from a brand with decades of motorsport validation.
