Intake Bolt Kit SBC 12PT 12pk

The Intake Bolt Kit SBC 12PT 12pk from ALLSTAR PERFORMANCE is a precision fastener set engineered for small block Chevy and Mopar A/B-series engine builds. Designed for technicians, engine builders, and performance enthusiasts who demand factory-grade reliability in critical intake manifold applications, this 12-piece kit eliminates the need for sourcing individual bolts and ensures uniform clamping force across the manifold seal. Proper intake fastener selection is fundamental to preventing vacuum leaks, oil seepage, and manifold gasket failure—common failure points in high-mileage or modified engines.

Each bolt in the Intake Bolt Kit SBC 12PT 12pk features a 12-point head geometry, which distributes load more evenly than traditional 6-point designs and reduces fastener deformation under torque cycling. The steel construction with zinc-oxide plating provides corrosion resistance in engine bay environments while maintaining structural integrity through thermal cycling. The 12-point head design also allows for precision socket engagement, minimizing rounding and ensuring repeatable torque values critical for proper manifold clamping force and gasket compression.

This kit is ideal for engine overhauls, intake manifold replacement, or performance builds where OEM bolt condition is questionable or fasteners have been cross-threaded during previous service. The 12-pack quantity covers most small block Chevy and Mopar A/B-series intake manifold configurations, eliminating the need for multiple small purchases. Recommended installation includes torque verification to manufacturer spec (typically 12–15 ft-lbs for intake manifolds) using a calibrated wrench to ensure even gasket seating and prevent coolant or vacuum leaks that compromise engine performance and reliability.
