• Twin independent variable camshaft timing (Ti-VCT)
• Cold-air induction
• Dual overhead camshaft (DOHC) cylinder head with
4 valves per cylinder
• Deep-skirt aluminum engine block and aluminum
cylinder heads help to reduce overall vehicle weight

• Electronic throttle control
• Deep-sump oil pan with 8-quart capacity and oil
change interval up to 10,000 miles
• Fail-safe cooling system
• Mated only to a 6-speed manual transmission
Boss 302-specific Enhancements
• Revised composite intake system with shorter
runners for high-rpm breathing; manifold includes
production number plate
• Forged aluminum pistons and upgraded connecting
rods for improved strength
• High-strength aluminum-alloy cylinder heads
with fully CNC-machined ports and chambers for
exceptional high-rpm airflow without sacrificing
low-speed torque
• Lightened valvetrain components
• Sodium-filled exhaust valves for improved heat
dissipation
• Race-specification crankshaft main and rod bearings
for improved high-speed durability
• Revised oil pan baffling for improved oil control
under cornering loads greater than 1.0 g, a situation
often seen in racing environments
• Quad exhaust system with two rear outlets and two
side outlets from the exhaust crossover
• Removable fog lamp covers within grille help improve
engine heat dissipation; covers can be removed on
track days with a screwdriver
ENGINEERING INSIGHT
quad Exhaust outlets
The Boss includes a quad exhaust system with two
rear outlets and two side outlets from the exhaust
crossover. This design sends the engine exhaust
through a set of metal discs acting as tuning elements
before the pipes terminate just ahead of the rear
wheel openings. The side pipes provide an authentic
V8 sound experience unlike any other Mustang.
NOTE: Discs are removable and include a spacer plate
sized to match aftermarket exhaust "dump" valves.

6-speed Manual Transmission Enhancements
• Gear spacing helps the driver keep the engine in the
torque "sweet spot"
• Racing-inspired clutch with heavy-duty friction
material for improved durability
Limited-slip Rear Differential
• Boss 302-specific carbon fiber clutch plates to help
improve durability and torque delivery
• Higher-performance 3.73:1 axle ratio
TORSEN Differential
®
• Available on the Boss 302 and included in the
Laguna Seca Package
• A full-time torque-sensing system designed to
improve power delivery to the rear wheels
• Differential continuously manages power delivery
between the rear axles, helping maximize traction
over a variety of road conditions
• A better balance of power delivery helps improve
overall vehicle handling and acceleration capability
• TORSEN differential uses a parallel helical
gear system
– Helical gear set is more robust than a limited-slip
differential with a clutch pack design

Suspension and Chassis Enhancements

• 19" aluminum racing wheels, painted black, with
staggered widths
– Staggered wheel widths, 9" front/9.5" rear, allowed
engineers to fit the widest tires to the chassis
• 5-way adjustable shock absorbers with Boss
302-specific tuning allow the owner to set the shock
absorbers to their preference
– Setting 1 is the softest and setting 5 is the firmest
• Boss 302-specific tuning of the electric power-
assisted steering (EPAS)
• Higher-rate coil springs than Mustang GT help
increase chassis response
• Lower ride height, 11mm front and 1mm rear helps
lower the vehicle overall center of gravity for
improved handling response
• Max-performance Pirelli PZero
tires for improved overall grip
• Stiffer suspension bushings than Mustang GT help
increase chassis response
• Strut tower brace helps increase chassis
structural rigidity
(1) Ford does not recommend using summer tires when temperatures
drop to approximately 40°F or below (depending on tire wear and
environmental conditions) or in snow/ice conditions. If the vehicle
must be driven in these conditions, Ford recommends using all-season
or snow tires.
