Back in the 1980's Detroit's auto manufacturers were transforming all there engine platforms to direct port fuel injection which included an entire array of new components such as fuel injectors, air intakes, mass air sensors and throttle bodies. When BBK founder Brian Murphy began selling products for this new breed of American Musclecar, it was the 1988 5.0L Mustang that he purchased as his first development vehicle. Whether carbureted or fuel injected the basic design of all engines is pretty straight forward, more air in & out efficiently as possible equals more horsepower. After starting with a new direct bolt in shorty and equal length design header, Brian and his team quickly started addressing the intake side which resulted in ported out throttle bodies and mass air meters. After a short successful period of offering these modified parts, our engineers soon began tooling up new high flow castings that would allow for more sizes and overall much better performance levels.
