1. Disconnect the negative battery cables.
Unlatch all four clips on the factory airbox.

gauge wiring harness, remove the restriction
gauge, and the rubber grommet. (N ote: retain
these parts for reuse.) Remove the air filter inlet

it is a tight fit. Be careful not to tear the factory
insulation around the radiator support.
2. Remove the factory airbox by separating the
inlet and outlet sections of the assembly.
5. STOP AND LOOK! If you have a tempera-
ture sensor like this, disconnect the t emper a-
ture sensor wiring harness, remove the sensor
from the tube (save it for reuse) and proceed to
step #8. The early production 2005 F-250 and F350 6.0 diesel trucks either came with a temperature sensor, or they came with a Mass Air Flow
(MAF) sensor . These pictures will help you determine which sensor you have. Whichever sensor you have, this Airaid Intake System will fit.
3. The factory airbox is held in place by two
rubber grommets. Pull straight up and remove
the box. (Note: make sure the factory grom-
mets remain in the lower airbox support.)
