Blox Racing BXIM-00307 Velocity Stack 4 Inch Composite Intake

The Blox Racing Velocity Stack incorporates race-proven intake technology designed to optimize airflow entering your engine's induction system. This performance component is engineered for both daily driven and competition vehicles, maximizing air flow rates while maintaining reliability.

Advanced Composite Construction:

Injection-molded from PA66 glass-filled nylon composite, this velocity stack offers significant advantages over traditional aluminum designs. The composite material dramatically reduces heat soak, preventing hot underhood temperatures from transferring to incoming air and degrading performance. The lightweight construction reduces mechanical stress on air induction mounts and components while maintaining structural integrity.

Key Features:

• 4-inch diameter composite velocity stack in black finish
• PA66 glass-filled nylon construction for superior heat resistance
• Designed to accept aftermarket air filters
• Lightweight design reduces stress on induction system mounts
• Race-proven trumpet design optimizes airflow velocity
• Significantly lower heat transfer compared to metal velocity stacks

The velocity stack's trumpet profile smooths airflow transition into the intake manifold, reducing turbulence and improving volumetric efficiency. Ideal for naturally aspirated builds seeking improved throttle response and top-end power.
