Intake Manifold Gasket Set GM LS

The FEL-PRO Intake Manifold Gasket Set for GM LS-Series engines is a factory-specification replacement gasket pair engineered to restore proper sealing between the intake manifold and cylinder head. This is critical maintenance for LS-platform engines, where manifold gasket failure leads to vacuum leaks, rough idle, reduced fuel economy, and potential coolant seepage. FEL-PRO's MS 96587 gasket set is manufactured to OEM tolerances and material standards, ensuring drop-in compatibility with stock LS-series port designs across Gen III, IV, and V platforms.

Each pair contains both gasket halves required for a complete manifold seal. FEL-PRO utilizes proven elastomer compounds formulated to withstand LS-series operating pressures and thermal cycling without degradation. The gasket thickness and material composition are matched to factory-cast aluminum manifolds and stock cylinder head configurations. Installation is straightforward: remove the manifold, clean all mating surfaces to bare metal, and seat the new gaskets with the manifold bolts torqued to specification. The gasket set weighs 0.65 lbs and ships in compact packaging suitable for immediate jobsite or shop deployment.

This gasket set addresses a known wear item on LS engines with higher mileage or those subjected to sustained boost pressures. Whether performing routine maintenance on a stock engine, rebuilding after disassembly, or sealing a manifold after removal for other work, the FEL-PRO MS 96587 delivers the sealing reliability expected of an OEM-specification component. Technicians and engine builders specify FEL-PRO gaskets for LS platform work because the brand's manufacturing process ensures consistent geometry and material performance across production batches.
