Federal Mogul MS91948 Fel-Pro Intake & Exhaust Manifold Gasket Set

The Federal Mogul MS91948 is a Fel-Pro intake and exhaust manifold gasket set engineered specifically for the demands of the automotive repair environment. Designed to deliver a reliable, long-lasting seal on both the intake and exhaust manifold mating surfaces, this set includes all the gaskets needed to complete the repair in a single kit.

Fel-Pro gaskets are application-specific, meaning each component is precision-designed to match the exact port geometry and bolt pattern of the target application. The gaskets are manufactured using proprietary materials that compensate for imperfect or worn sealing surfaces — a common challenge in high-mileage engines — without requiring additional sealer compounds.

Key Features:

• Complete set — includes all intake and exhaust manifold gaskets required for the repair
• Application-specific design — engineered for a precise fit and optimal sealing on the target application
• High-temperature resistant construction — resists blow-out and thermal degradation from exhaust heat cycling
• No additional sealers required — proprietary materials conform to surface imperfections for a clean, dry installation
• Torque retention — premium gasket material maintains proper clamp load across heat cycles
• Fel-Pro quality — a Federal-Mogul brand trusted by professional technicians and engine builders for over a century

A failing intake manifold gasket can allow vacuum leaks that cause rough idle, lean misfire codes, and reduced throttle response. A compromised exhaust manifold gasket can permit dangerous exhaust gas intrusion and skew oxygen sensor readings, affecting emissions and engine performance. The MS91948 set addresses both sealing points in one package, making it an efficient solution for manifold service or engine reconditioning work.
