BBK Performance Parts - 2011 Ford Mustang GT Cold Air Intake Kit Designed to work without modifications or any tune, this BBK cold air kit is optimised to work with the 2011 Mustang GT factory computer settings – BBK ‘s latest cold air intake kits for the popular 2011 Ford Mustang delivers as much bang for the buck as our 2011 Throttle Bodies. Testing on dozens of stock 2011 Ford Mustang GT models has shown consistent gains of 15-16 rear wheel horsepower with no other add-ons and the stock computer program. This compares to the 8-9 horsepower BBK engineers noted with other brand units and a power programmer. This high level of performance with the stock program is achieved by utilizing a custom integral mass air housing which is machined into our new aluminum casting and features a calibration of the factory mass air. While BBK engineers have seen some gains with a power programmer when used with a variety of modifications – they have not been able to achieve much more than what this cold air intake kit delivers
