Product Details & Technical Specifications

Why Upgrade Your Silverado or Sierra Intake System?

The KYOSTAR Cold Air Intake System features a black curved intake tube, gray cone filter, and open-style heat shield for a distinctive performance-inspired appearance.

Actual intake sound and airflow behavior depend on the engine configuration, factory sensors, and complete intake system installation.

No specific horsepower increase, torque gain, throttle response improvement, or fuel economy benefit is claimed without verified test data.
