Aftermarket filtration devices tailored to specific vehicle makes and models represent a deviation from original equipment manufacturer (OEM) components. These units replace the factory-installed part with one designed to enhance engine performance or provide a unique aesthetic. Functionally, they serve the same primary purpose: to filter incoming air before it enters the engine.
The adoption of these specialized components can offer several advantages. Improvements in airflow, contributing to increased horsepower and torque, are often cited. Additionally, certain designs offer superior filtration capabilities, protecting the engine from harmful contaminants. Historically, modifications of this type have been popular among automotive enthusiasts seeking to personalize and optimize their vehicles.
