Good Maintenance Practices - Section 1 - Bullet 1
Before purchasing and installing an engine intake manifold, make sure it is the correct size and fit for your vehicle.

Keep the air duct assembly clean and properly sealed and the engine air filter clean or changed at every oil change, or more frequently if the vehicle is operated in dusty environments.

Do not run an overheated engine, or damage to components or gaskets could occur.
Good Maintenance Practices - Section 1 - Bullet 9
Regularly inspect engine intake manifolds for signs of damage or wear, and replace them if signs of damage are found.
