BMC Direct Intake Airsystem (DIA)

The operation philosophy of BMC top range product, the Carbon Dynamic Airbox (CDA), is utilised in the DIA using less exotic material and therefore being more economical. This has enabled the production of a system that still gives more performance than a normal shielded cone filter.

The DIA consists of a plastic airbox containing an air flow deflector and a reusable filter element. Also supplied in the universal kit there is a flexible tube to carry cool air to the Airbox inlet.

The DIA70-130 is universal and is supplied with a basic fitting kit, see pictures below. The DIA70-130 is suitable for most makes/models of car under 1600cc. For larger engines or engines producing more than approximately 140bhp we suggest installing the larger DIA85-150
