Add 35 to 100 hp (depends on application). Provides a cooler, denser air charge allowing more timing, less fuel and reduced chance of detonation. Features exclusive double pass, low restriction air/water core. Uses water/glycol mix as its cooling medium for street and road race applications (ice water may be used for drag racing purposes). Compact air to water design allows it to be optimally placed in the system with minimal pressure loss. Battery relocation is required and is not included in the system
