Good To Know

Q: Can these gaskets be reused after removal? A: No, intake gaskets compress to form their seal and should always be replaced once the manifold is disassembled. Reusing them can lead to immediate vacuum leaks.

Q: What are signs of a leaking intake gasket? A: Common symptoms include a rough engine idle, illuminated check engine light, lean fuel codes, or whistling noises from the engine bay.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
