Bully Dog introduces its Stage 2 intakes for 2012. They are now made for the 5.9-liter Cummins and Ford 6.0- and 6.7-liter Power Stroke engines, and for Ford F-150s equipped with the 5.0-liter or EcoBoost. The intakes pull air from cooler sources, keeping hot air out of the intake stream, and each one uses a high-flow air filter. The intakes are said to improve fuel economy and increase horsepower and torque. They cost $340-$370, depending on application.
