Our Series 2 outsells our Series 1 because it features larger turbo wheels, a bigger housing opening, and a precision-balanced blade wheel. These upgrades deliver that sought-after whistle everyone wants in their 6.0 Powerstroke turbos. Plus it can handle a touch more HP over the series 1, making it the preferred choice.
