Features and Benefits:

  • Evenly distributes the combustion mixture (or just air in a direct injection system) to each intake port in the cylinder head for proper function
  • GM-recommended replacement part for your GM vehicle's original factory component
  • Manufactured to GM OE specification for fit, form, and function
  • Offering the quality, reliability, and durability of GM OE
  • – Before purchasing and installing an engine intake manifold, make sure it is the correct size and fit for your vehicle.
  • – Clean the engine's exterior as needed - buildup of oil and dirt can cause the engine to run hot or hide leaks.
  • – Do not run an overheated engine, or damage to components or gaskets could occur.
  • – Have your vehicle inspected as soon as possible if the 'Service Engine Soon' light illuminates.
  • – Have your vehicle inspected immediately if the 'Service Engine Soon' light flashes rapidly, as this could indicate an engine misfire condition which may damage your engine and/or engine emission components.
  • – 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.
  • – Refer to the engine service manual for proper torque specifications.
  • – Regularly inspect engine intake manifolds for signs of damage or wear, and replace them if signs of damage are found.
  • – Tighten the intake bolts to the proper manufacturer's specifications, and do not overtighten.
