Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter
element edges between the air filter
housing and cover. This could cause
filter damage and allow unfiltered
air to enter the engine if not
properly seated.
6. Replace the air filter housing
cover and secure the clamps.

WARRANTY COVERAGE
The Shelby GT500 carries the same New Vehicle Limited Warranty as
other Ford Mustang models. This information is covered in its entirety in
the Ford Motor Company Warranty Guide.
Warranty service for the Shelby GT500 or any SVT vehicle can be
obtained at any Ford or Lincoln Mercury dealer nationwide.
SVT does not recommend modifying or racing SVT vehicles, as they are
designed and built to be driven as delivered from the factory. The Ford
Motor Company Warranty Guide discusses vehicle usage and the
installation of aftermarket parts and their effect on warranty coverage as
follows:
Repairs are not reimbursable under warranty when damage is caused by:
•misusing the vehicle, such as driving over curbs, overloading, racing,
or using the vehicle as a stationary power source.
•altering or modifying the vehicle — including the body, chassis, or
components — after the vehicle leaves Ford’s control.
•non-Ford parts installed after the vehicle leaves Ford’s control,
including, but not limited to, cellular phones, alarm systems and
automatic starting systems.
Please see the Warranty Guide for complete information.
In the event the vehicle is intended for track use, and the loss of
warranty coverage is not of concern, the following powertrain durability
modifications are recommended:
•install transmission oil cooler. Permanent damage to the transmission
will result if the vehicle is subjected to competition conditions without
installation of a transmission oil cooler.
•install rear differential cooler. Permanent damage to the rear
differential will result if the vehicle is subjected to competition
conditions without installation of a differential cooler.
Additionally, perform Multi-Point Inspection and the inspections outlined
in the 120,000 mile Normal Maintenance Schedule outlined in the
Scheduled Maintenance Guide. Refer to the Vehicle Service Manual for
removal and installation procedures. Replace with Genuine Ford and
Motorcraft service parts as needed.
These modifications will not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications will render repairs
non-reimbursable under the New Vehicle Limited Warranty.
