Ford Racing's 5.0L Boss Intake Manifold paired with Steeda's proven high flow cold air intake system and custom SCT tuning produce awesome, usable top end horsepower gains without sacrificing overall torque vs a stock Mustang GT.

The resulting power increase gives you fierce acceleration while preserving smooth driveability and control during part throttle everyday use.

Road racers will appreciate the linear, smooth torque curve allowing for more consistent corner exit. Drag racers and road racers alike will appreciate the top end horsepower for excellent 1/4 mile performance in drag racing and hard acceleration on long straights on road courses.

Expect peak power gains in excess 50 horsepower over a stock GT on stock exhaust, but peak gains don't tell the whole story. With the Boss intake top end power never falls off, giving you a car that just keeps pulling hard shift after shift. It is an intoxicating feeling you will enjoy over and over again.

Besides the parts in this package, you will need the following parts from your local Ford dealer for a complete installation. Road racers will appreciate the linear, smooth torque curve allowing for more consistent corner exit.
