The BBK brand has been synonymous with bolt on performance for the modern muscle car since its beginning in 1988. In fact it was the founders Brian & Ken Murphy that designed and developed the first aftermarket air intake systems & performance throttle bodies for the then newly fuel injected 5.0L Mustang and TPI Camaro models. Back then nobody even knew what an air intake or throttle body was because people were just learning about these modern day fuel injected pony cars that Detroit had begun to produce. Fast forward to today and many enthusiasts have only grown up on computer controlled fuel injection with a vocabulary full of upgrade items such as throttle body, air intake & mass air meter and have never driven a carbureted equipped vehicle. It’s this early experience and years of research & development, along with millions of dedicated enthusiasts that have allowed the BBK brand to grow into the largest source of modern day performance products for today’s cars & trucks.
