BBK: BBK enters the fray with its SSI intake manifold kit, including hi-flow billet fuel rails to optimize fuel movement. The SSI features an open runner blueprint allowing for a cooler air mixture and equal airflow distribution to the lower manifold. It also features a removable baffle plate to ease access to the fuel runners if installing nitrous jets. The SSI can see gains of up to 30HP on an otherwise stock motor.
Edelbrock: Edelbrock is another big name in the Mustang aftermarket business. In this situation, Edelbrock offers 3 different intake manifolds depending on your needs, the Performer, Performer RPM II and the Victor – all EFI manifolds.
Performer Manifolds: The Performer is based on a rectangle style shape similar to the stock piece but the similarities end there. The Performer will outrun the stock intake any day, with increases of 37 HP a real possibility and no loss of low range torque. The Performer is a great street car choice because it operates within the stock rev range off idle to 5500 rpm. The Performer RPM II manifold offers superior performance for engines built to spin a little higher, between 1500-6500rpm. This too is a solid choice for those looking to mix their car between the street and track. Edelbrock recommends a 70mm throttle body to use in conjunction with the Performer and Performer RPM II. Furthermore, they both feature a removable plate to gain instantaneous access to the internal runners for easy porting.
