BMC ACOTASP-14 Carbon Fiber Oval Trumpet Airbox Air Filter Housing - Kit

The BMC ACOTASP-14 Oval Trumpet Airbox (OTA) is a complete high-performance engine air aspiration and filtration system designed to replace the factory airbox. This premium kit features an oval-shaped carbon fiber airbox construction containing a cylindrical air filter with a dynamic inlet, delivering superior airflow and performance gains over restrictive OEM air filtration systems.

Advanced Trumpet Technology:

The innovative "Trumpet" element positioned inside the airbox near the air outlet optimizes airflow conveyance to the engine while reducing turbulence. This design reduces pressure drop along the engine aspiration line and takes advantage of dynamic air pressure created by vehicle speed. Unlike stock airboxes that operate in a depression regime through reduced-section tubes, the OTA system works in a pressure regime, providing constant, high-volume air delivery to the engine.

Key Features:

• Dual carbon fiber oval airboxes with low thermal conductivity for heat insulation
• Two cylindrical air filters with multi-layer pre-oiled cotton gauze filtering material
• High filtration efficiency down to 7 microns while maintaining minimal pressure drop
• Washable and reusable filters with lifetime durability
• Complete replacement kit including air hoses and all mounting hardware
• Constructed using BMC's Full Moulding process developed by their F1 R&D team
• Oval shape design offers superior installation versatility

What's Included:

• 2 carbon fiber oval trumpet airboxes
• 2 cylindrical air filters (pre-oiled)
• 2 air intake hoses
• Complete mounting hardware

BMC air filters can be regenerated using the appropriate cleaning and re-oiling kit (sold separately), ensuring long-term performance and value. The carbon fiber construction provides excellent durability while reducing heat soak from the engine bay.
