PRL's High Volume Cold Air Intake (HVI) utilizes a 6" or 4" cone filter, and on some applications billet 1 or 2-piece MAF housing with velocity stack to allow maximum airflow while delivering proper fuel trims. The HDPE rotomolded air box utilizes the factory air duct and seal for optimal airflow and heatsoak reduction. Custom molded 4-ply silicone allows for all components to be safely attached without obstructing airflow. No tune required (except on Race MAF versions).

Key Features:

• Well sealed and allows for very high air volume.
• Performance air filter in combination with rotomolded air box reduces heatsoak and the chance of sucking in hot engine air.
• Quality materials and constructions.
• CNC machined billet aluminum MAF housing provides factory-spec fuel trims (-4% of factory STFT & LTFT) for optimal driveability and performance.
• Great overall power results with no tuning required (except on Race MAF versions).
• Race MAF housing is designed for high-horsepower builds that will exceed factory MAF values. Requires a tune to properly scale MAF output. Rated at 600+ horsepower, and offers a 47% increase in airflow volume over the factory MAF housing or Street HVI MAF.
