BMC Oval Trumpet Airbox ACOTA70/85L170-B-WP Waterproof Carbon Fiber Cold Air Intake Kit

Product Description:

Maximize Engine Performance with the BMC Oval Trumpet Airbox ACOTA70/85L170-B-WP:

The BMC Oval Trumpet Airbox ACOTA70/85L170-B-WP is a premium Waterproof (WP) cold air intake system designed to maximize engine airflow, improve filtration efficiency, and enhance overall engine performance. Engineered as a complete replacement for the factory airbox, the OTA (Oval Trumpet Airbox) kit combines a lightweight carbon fiber airbox, dynamic air inlet, and a high-flow washable BMC air filter for superior engine breathing.

Developed as part of BMC's Waterproof (WP) range, this intake system is specifically built for demanding environments including off-road trails, desert terrain, muddy conditions, and water crossings. Unlike conventional factory airboxes that operate under a negative pressure system, the OTA utilizes a dynamic pressure intake, allowing a greater volume of cool, pressurized air to reach the engine while reducing intake restrictions.

The system incorporates BMC's innovative Trumpet Airflow Technology, positioned inside the carbon fiber airbox near the outlet. The trumpet-shaped diffuser optimizes airflow, minimizes turbulence, and reduces pressure loss along the intake path, resulting in improved throttle response, enhanced combustion efficiency, and increased engine performance.

Inside the airbox is a multi-layer pre-oiled cotton gauze air filter, engineered to provide exceptional filtration against dust, sand, debris, and other contaminants while maintaining maximum airflow. The filter is fully washable and reusable using the BMC regeneration kit, ensuring long service life and lower maintenance costs.
