The ALTA Cold Air Box is formed from laser cut aluminum sheet metal then CNC bent to perfection. Then finished in a rich black texture powder coating for long term protection and an O.E.M. look. Our airbox seals to the underside of the hood preventing under hood heat from entering the intake airstream. With an ALTA intake system your car will make a throaty, deep tone on throttle that is undeniably modified. You will be able to hear your supercharger whining, both stock and aftermarket.

Our high flow foam filter reduces intake restriction and increases the surface area from which the engine can ingest clean air. Unlike cotton and gauze type filters, foam filters allow for multi-layer filtration. The ALTA Performance foam based filter will trap dirt within the filter at many different levels. This allows for better particulate restriction and will not reduce HP as the filter gets dirty.

ALTA Cold Air Intake has proven a 10-12 WHP gain many times over.

The ALTA Cold Air Intake System for R53 6-speed Automatic is available in black or red texture powder coating.
