INSTALLATION
1) Disconnect the vehicle's negative battery cable.
2) Remove the inter-cooler tubes from the vehicle, held in place by hose clamps. (see fig. 1)
3) Remove the bolts holding the airbox to the body. There are 2 on the airbox and 1 on the mass-air bracket.
4) Loosen the hose clamp where the intake hose connects to the mass-air sensor.
5) Carefully unplug the power cable from the mass-air sensor (held in place by a small spring-clip) and remove the wire from
the mass-air sensor (hooked to a small bracket with a plastic clip).
6) Un-hook the vacuum hoses from the mass-air bracket. Do not remove them from the vehicle.
7) Remove the mass-air sensor and airbox as an assembly.
8) Unclip the airbox lid and remove the air filter.
9) Remove the nuts holding the mass-air sensor to the airbox (there are metal locking tabs over the nuts that must be bent
out of the way with a straight-bladed screwdriver).
10) Remove the foreign-object-deflector screen and separate the mass-air sensor from the airbox.
**CAUTION** The honeycomb material in the mass-air sensor is very fragile. Be careful not to damage it.
11) Remove the 4 studs from the mass-air sensor. If you thread two nuts on to the stud, and tighten them together, you can
then back the stud out with the bottom nut.
