5″ Competition Air Shutoff with Filter Assembly

Your winning run depends on two things: Airflow and Safety.

This 5-inch Air Shutoff and Filter Assembly is the ultimate mandatory upgrade, engineered to deliver unrestricted airflow while providing instant, positive engine shutdown for competition compliance.

Uncompromised Airflow. Unmatched Safety.

1. Max-Flow Inlet & 5″ Diameter

Built around a massive 5-inch internal diameter, this system ensures your  turbo is fed the maximum air volume it demands, without the restriction of undersized components.

• Turbo Efficiency: Optimized for large diesel turbos used in competition classes

• High-Volume Filter: Paired with a high-capacity, low-restriction filter element designed to protect your turbo and engine internals from track debris without choking performance.

2. Competition Safety Certified (Air Kill)

Meeting safety regulations is non-negotiable. Our robust Air Shutoff (ASO) mechanism is built for instant activation, safeguarding your truck and meeting all necessary sanctions.

• Dual Activation Ready: Designed to accept the mandatory sled kill cable and often includes hookups for a driver-activated cable for peace of mind.

• Essential for Compliance: This setup fulfills the mandatory “air kill” requirement for virtually all major truck and tractor pulling associations.

3. Built for the Track

• Durable Construction: Machined from 6061 billet aluminum to withstand the vibration and stress.

• Secure Mounting: Designed for direct, secure mounting to the turbocharger inlet using a V-Band for a zero-leak connection.
