BMC ACOTASP-18 Oval Trumpet Carbon Fiber Cold Air Intake System

The BMC ACOTASP-18 Oval Trumpet Airbox (OTA) is a complete high-performance cold air intake system designed to replace the factory airbox. This premium intake kit features an oval-shaped carbon fiber airbox housing a cylindrical cotton gauze air filter with a dynamic inlet for maximum airflow and engine protection.

Key Features:

• Oval carbon fiber airbox construction with 5-layer composite for thermal insulation and lightweight strength
• Innovative "Trumpet" technology inside the airbox optimizes airflow to the engine and reduces turbulence at the outlet
• Dynamic inlet operates in a "pressure regime" rather than the restrictive "depression regime" of stock airboxes
• Multi-layer pre-oiled cotton gauze filter provides superior filtration efficiency with minimal pressure drop
• Washable and reusable filter with lifetime durability - never needs replacement
• Complete bolt-on kit includes everything needed to replace the factory air intake system
• Constructed using BMC's "Full Moulding" process developed by their F1 R&D team

Performance Benefits:

Unlike restrictive factory paper filters that limit airflow, the BMC OTA system takes advantage of dynamic air pressure created by vehicle speed to deliver a constant, high-volume supply of cool air to the engine. The proprietary Trumpet design inside the airbox minimizes pressure drop along the intake path while optimizing fluid dynamics for improved throttle response and power gains. The oval shape provides exceptional installation versatility in tight engine bays.

Maintenance:

The cotton gauze filter element can be easily cleaned using BMC's washing kit (sold separately) and re-oiled for continued use. BMC recommends regenerating the filter every 12,000-15,000 miles to maintain optimal performance. The carbon fiber airbox requires no maintenance and is designed to last the lifetime of the vehicle.
