When you replace the upper Intake Manifold you need to remove the evap purge solenoid valve, Intake Manifold tuning valve, and Throttle Body. Secure upper Intake Manifold gaskets on the lower Intake Manifold by using fir tree retainers. Use threadlock on upper Intake Manifold bolts before attaching the upper manifold where torque should reach 23 n.m (17 lb ft). You should install the Throttle Body and Intake Manifold tuning valve and evap purge solenoid valve after upper manifold installation. Many steps remain to finish the Intake Manifold installation. After map sensor electrical connector reconnection, install engine harness bracket retaining bolt then connect etc electrical connector. The installation process involves reattaching the Brake Booster Vacuum Hose to the Intake Manifold then connecting the manifold tuning valve electrical connector alongside the pcv line to the top of the Intake Manifold and the evap canister purge line. Construct the Intake Manifold insulator and attach both the air cleaner outlet duct along with the fuel injector sight shield.

Various types of intake manifolds include those meant for carbureted engines, Throttle Body Injection, multiport fuel injection, and Gasoline Direct Injection and they differ in their ways of aerating the fuel. Sedan earlier models of manifold were mostly of cast iron or aluminum more recent ones are of light plastic composites for better fuel efficiency and heat management. Another set of intake manifolds is designed as upper and lower halves with gasket, coolant channels and locations of thermostats. Those usually used in the are likely to deliver a higher horse-power and torque due to differences in the runner shape and dispersion of airflow. Therefore, depending on the engine configuration or modification, the drivers can improve the efficiency of the manifold by installing the modern aluminum manifold.
