Installation steps (for reference only, subject to actual conditions):
1. Disconnect the negative terminal of the battery (-).
2. Loosen the two clamps that secure the intake pipe to the throttle body and air box.
3. Release the connecting rod of the cable attachment from the throttle.
4. Disconnect the electrical connections of the idle air control, thermal protection system, and intake manifold absolute pressure sensor.
5. The throttle body has been installed.
6. Unscrew the intake manifold from the valve body and remove it.
(Note: Some models of throttle bodies do not have MAP sensors installed, and for these vehicles, we provide placement of vacuum covers.)
Reminder:
Before installation, in zero power or very slow acceleration crawling mode, the red flashing light and traction control light are on.
After installation, first turn the ignition switch to the "on" position for a few seconds, then turn it back, and repeat the operation again before it can be used.
Advantage:
It can optimize the intake and exhaust cold air.
