PERMADRYPLUS® INTAKE MANIFOLD GASKETS
1: Steel carrier (vs. OE plastic) provides strength and is resistant
2: Proprietary rubber sealing compound withstands all coolants.
3: Locating tabs assure proper positioning.
4: Self-centering torque limiters prevent damage during installation.
5: Extra sealing beads eliminate potential leak paths.
Problem-solving Fel-Pro® PermaDryPlus® gaskets feature advanced technologies designed to address sealing problems unique to the aftermarket repair environment. Their construction includes sophisticated molded rubber designs, rigid carriers and sealing advances to help the technician complete the repair faster and more easily with a permanent seal.
Fel-Pro® PermaTorque® type construction — Many Fel-Pro intake manifold designs feature rubber/fiber facing over a steel core for leak-free sealing and easy removal when necessary.
Leaks at the intake manifold are a common engine problem. A “vacuum leak” allows too much air to enter the engine. This can lead to driveability problems such as rough idling and stumbling on acceleration. Vacuum leaks at the intake manifold can also cause:
• Hot-running engine
• Decreased valve life
• Increased nitrous oxide (NOX) emissions
An intake manifold coolant leak is also a possibility in today’s engines. Where applicable, Fel-Pro offers a premium PermaDryPlus® problem-solving gasket for applications that have proved specifically problematic in the aftermarket repair environment.
Typically, upper and lower manifold gaskets are included in Fel-Pro intake manifold sets. For certain fuel-injection applications, however, upper intake manifold sets are offered. These sets include intake manifold-to-plenum gaskets, as well as other required plenum gaskets. Choose an upper manifold set when working on the fuel-injection system or on some valve cover repairs where it is necessary to remove parts of the fuel-injection system.
