Exhaust & Intake Parts

Intake and Related Engine Breathing Components

Intake and related engine breathing components, such as intake manifolds, high-flow air filters, and reed valves, are designed to improve engine airflow and efficiency. High-flow filter designs boost air volume and velocity for quicker throttle response and more complete combustion. Tuned intake manifolds and reed valves optimize the air–fuel mixture flow, improving engine breathing and overall performance (while maintaining proper filtration and engine protection).
