The VIPER kit uses ‘velocity air force 'to direct cold air directly into the engine. The cold air feed takes air from behind the grill straight into the VIPER 's 100mm diameter inlet, swirling it through a unique Pipercross velocity filter contained within a carbon fibre heat shield, and then into a ram pipe to increase it 's pressure before feeding it into the induction system.

The carbon fibre heat shield protects the air charge from under bonnet heat keeping it cool -and therefore more dense - thus introducing more oxygen into the combustion mixture, giving increased power.

A Great addition for normally aspirated engines...great gains and looks fantastic
