Remove the EGR valve from the old EGR spacer. Clean the EGR valve mating surface. Put your new EGR gasket on the new EGR spacer, and install the EGR valve using the supplied hardware. Put your EGR spacer to intake gasket onto they intake. Slide on the EGR spacer, followed by the throttle body to EGR spacer gasket, and finally the throttle body.

Install the four throttle body retaining nuts. Clip your throttle cable back on to the throttle body. Reinstall the two throttle cable bracket bolts. Plug-in the EGR connector and reconnect the EGR vacuum line. Hook up the EGR spacer coolant hoses. Reinstall the idle air control motor and plug in the connector. Reconnect the valve cover hose.

Remove the throttle position sensor from the old throttle body, and install it on the new throttle body. Reconnect the throttle position sensor connector. Reinstall your air inlet tube and tighten the clamps. And plug in your mass airflow meter.
