Designed to work without modifications or any tune, this BBK cold air kit is optimised to work with the 2010 Mustang GT factory computer settings – BBK ‘s latest cold air intake kits for the popular 2010 Ford Mustang delivers as much bang for the buck as our 2005-2010 Throttle Bodies. Testing on dozens of stock 2010 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.
