BMC ACOTASP-19 Carbon Fiber Oval Trumpet Airbox Complete Intake System

The BMC ACOTASP-19 OTA (Oval Trumpet Airbox) is a complete high-performance air intake and filtration system that completely replaces the factory airbox. Engineered with a lightweight carbon fiber oval-shaped housing, this system delivers maximum airflow while providing exceptional thermal insulation and heat soak protection.

Key Features:

• 5-layer carbon fiber construction for superior rigidity and heat resistance
• Innovative internal "Trumpet" design optimizes airflow and reduces turbulence at the air outlet
• Dynamic inlet system operates in "pressure regime" rather than restrictive "depression regime"
• Pre-oiled multi-layer cotton gauze filter provides high filtration efficiency with minimal pressure drop
• Washable and reusable filter with lifetime durability
• Filters particles down to 7 microns while maximizing air volume
• Oval shape provides versatile installation options in tight engine bays
• Complete bolt-on kit replaces OEM airbox entirely

Unlike restrictive factory paper filters that create pressure drops and limit engine performance, the BMC OTA system leverages dynamic air pressure created by vehicle speed to deliver a constant, high-volume supply of filtered air to the engine. The precision-engineered trumpet element inside the airbox guides airflow smoothly to minimize turbulence and pressure loss throughout the intake tract. Built using BMC's Full Moulding process developed by their Formula 1 R&D team, this intake system delivers measurable performance gains while maintaining superior engine protection.
