This is a replacement O-ring gasket for your LSJ intake manifold end plate. This is the O-ring that goes around the laminova cores and seals between the manifold and the end plate.
The stock gasket is discontinued and they may grow or crack over time. This O-ring is a quick install that should be done when servicing the laminova cores or switching to a dual pass end plate.
You may find that a small dab of RTV helps the gasket stay in place when installing.
