An induction system component, primarily found on General Motors vehicles, features a housing with two intake ducts. These ducts draw in ambient air from separate locations, typically near the front of the vehicle. The design aims to provide a greater volume of cooler air to the engine’s carburetor or throttle body compared to a single-snorkel or open-element system. A typical application can be seen on performance-oriented models from the 1960s and 1970s.
The utilization of this type of air cleaner can contribute to improved engine performance, particularly in terms of horsepower and torque. The cooler, denser air charge promotes more efficient combustion. Historically, it represented a move towards optimized airflow management in internal combustion engines, coinciding with the era’s focus on maximizing output.
