Because your intake manifold is subjected to extreme vibrations and heat, you can expect that the mounting hardware will soon wear out. At the top of the list is its gasket. Although your factory intake manifold gasket is designed to withstand the excessive heat produced during the combustion operation in your engine, it can only take so much. Over time, it will get blown and leaks will be possible. If this is actually happening now, get a direct-fit replacement set. For the best intake manifold gasket set for your vehicle, make sure you check on the quality of its material and manufacturing technology.
Materials commonly used in manufacturing an intake manifold gasket set
Rubber is the most common material used in making automotive gaskets. This is an elastomer with very high flexibility and water resistance. A gasket made of rubber is an inexpensive alternative to the more innovative PTFE or Teflon-made gasket. If you are looking for a reliable but inexpensive replacement for your factory gasket, you will never go wrong with ones made of rubber.
Metal is a durable material used for making automobile gaskets. It is perceived to solve blowing issues of rubber-made gaskets, but it is also a good conductor of electricity and heat that can eventually cause overheating to aluminum cylinders. If you have an equally malleable and ductile metal engine, this could be the best choice for you.
Nitrile rubber is another good material used in making gaskets. It is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. It differs from rubber because it can resist oil, fuel, and other chemicals. Nitrile rubber is also a bit pricey when compared to natural rubber, so expect to shell out more if you are choosing an intake manifold gasket set made from this material.
Silicone is also a synthetic compound used in the production of automotive gaskets because of its very high resistance to water and heat. If you want a longer-lasting performance gasket for your intake manifold, make sure it's made of silicone.
Polytetrafluoroethylene (PTFE) or Teflon is among the newest materials used in making automotive gaskets. It is a fluorocarbon solid with high electronegativity of fluorine, making it hydrophobic. PTFE has very low friction coefficients to solids, too. Intake manifold gasket sets made from this material is your best choice.
