First off The Cold Air Induction : Fits all 2011, 2012, 2013 and 2014 Mustang GT 5.0 and Boss 302. This BBK Performance cold air kit is available in the Black Out Series (part# BBK-17685) or a polished chrome finish (part#1768) both offer the same great performance but with a different look - add a throttle body and your are really looking at great improvements in horsepower and torque along with improved throttle response across the RPM range with significant gains in the 4300 RPM range over stock - see the Dyno sheet in the video.
The BBK Power Plus throttle bodies are offered in 85mm or 90mm versions, while the larger version is recommended for the Boss 302 or supercharged applications.
Please note both of these items will perform on your car without any tune including the cold air intake systems SCT does have BBK specific tunes that will however allow you to get even more horsepower and torque from these parts but they are not required - your car will run great with the stock tune as well.
