BMC Oval Trumpet Airbox (ACOTA70/85 Series) – Cold Air Intake for Engines Above 1600cc

Oval Trumpet Airbox — engineered for engines above 1600cc, in two body lengths.

The BMC Oval Trumpet Airbox — ACOTA70/85 series is BMC's motorsport-derived intake system for engines above 1600cc, available in 170mm and 200mm filter body lengths with Black or White Pearl finishes. The 70/85mm inlet range covers the airflow demands of larger 4-cylinder, turbocharged, and V6 engines, while the oval trumpet filter geometry maximises surface area within the constraints of larger engine bays.

Every variant uses the same sealed cold-air housing principle: all intake air is drawn from outside the engine bay, completely isolating the filter from hot underbonnet air.
