Intake Gasket Set - SBM w/Steel Core

The Intake Gasket Set - SBM w/Steel Core (FEL-PRO 1213 S-3) is a premium gasket solution engineered for Small Block Mopar engines requiring precise intake manifold sealing. This gasket set is essential for mechanics and enthusiasts rebuilding or servicing their classic and modern Mopar powerplants, where intake manifold leaks can compromise vacuum integrity, fuel mixture control, and overall engine performance. Whether you're diagnosing a persistent coolant weep or performing a complete engine rebuild, this OEM-quality gasket set delivers the reliability expected from FEL-PRO's decades of automotive sealing expertise.

Constructed with FEL-PRO's proven Printoseal technology and a steel core laminate, this gasket set features a 0.065-inch thickness optimized for the rectangular port geometry common to Small Block Mopar manifolds (1.16 x 2.27 inch ports). The steel core reinforcement prevents blowout under cylinder pressure cycles and thermal cycling, a critical factor when dealing with vintage engines or high-performance builds that see temperature swings. The laminate construction ensures consistent sealing surface contact, eliminating the chattering and micro-leaks that plagued early cork or paper-only designs. This precision engineering guarantees a tight seal on every combustion stroke while maintaining dimensional stability across the engine's operating range.

Technicians and DIY builders working on 318, 340, 360, and 383 Small Block engines will appreciate the straightforward installation and immediate confidence this kit provides. The gasket set's compact footprint (5.8 x 0.65 x 26.95 inches) fits standard intake manifold bolt spacing, making it compatible with factory cast-iron and aluminum performance manifolds alike. Installation requires only basic hand tools and attention to proper torque sequencing—critical for achieving the clamp load necessary to activate the steel core's sealing properties. For anyone restoring a Dodge, Plymouth, or Chrysler performance vehicle, or upgrading an existing build with proven sealing technology, this FEL-PRO gasket set represents the best balance of durability, cost, and ease of installation.
