A Guide to Selecting the Best aem performance ram air kit
Understanding the Ram Air Principle
The primary distinction between a standard intake and a ram air kit is the utilization of dynamic pressure. A high-quality kit is designed to capture air from a high-velocity area—often through a specialized front bumper duct or a fender vent—and channel it directly into the throttle body with minimal turbulence. When shopping, you must ensure the kit is designed for 'ram air' induction rather than just 'cold air' induction. A true ram air kit focuses on the velocity of the incoming air, which can significantly improve throttle response and top-end power during high-speed driving.
Airflow Dynamics and Material Construction
The materials used in the construction of the intake piping are critical to maintaining air temperature and velocity. Look for kits that utilize heat-shielding technology. High-performance kits often feature polished aluminum or high-grade composites that resist heat soak from the engine bay. Heat soak is the enemy of performance. If your intake pipes absorb engine heat, you are essentially feeding your engine hot, less-dense air, which negates the benefits of the upgrade. Additionally, check the diameter of the intake tubing. The piping should be sized correctly for your engine's displacement to ensure smooth airflow without creating restrictive bottlenecks or excessive turbulence.
Filter Media and Maintenance Requirements
A kit is only as good as its ability to breathe. You will typically encounter two types of filtration: dry media and oiled media. Oiled filters are often preferred in high-performance applications because the oil can trap finer particulates, but they require more disciplined maintenance to ensure they do not over-saturate and interfere with the Mass Air Flow (MAF) sensor. Dry filters are easier to clean and maintain but may have slightly different flow characteristics. When choosing your kit, consider your driving environment. If you frequently drive in dusty or high-debris areas, the longevity and cleaning frequency of the filter media should be a primary decision factor.
Compatibility and Installation Complexity
Performance kits are rarely 'one size fits all.' Even within a specific vehicle make and model, different engine configurations (such as turbocharging vs. naturally aspirated) require vastly different intake geometries. Ensure the kit is specifically engineered for your vehicle's specific induction path. Furthermore, consider the installation complexity. Some kits are 'bolt-on' and require no modifications to the existing airbox housing, while others may require cutting into the bumper or relocating existing sensors. Always verify if the kit includes the necessary hardware, such as specialized clamps, silicone couplers, and sensor relocation brackets, to avoid mid-project trips to the hardware store.
The Role of Sensor Integration
Modern engines rely heavily on precise data from the Mass Air Flow sensor to manage fuel trim and ignition timing. A poorly designed intake can cause 'turbulent air' to hit the sensor, leading to erratic readings, check engine lights, or even stalling. A premium performance kit will feature a smooth, predictable transition of air as it passes the sensor location. If a kit lacks a dedicated mounting point for your factory sensor, it is likely not a professional-grade solution and could compromise your engine's drivability.
