Prevent intake manifold leaks with ARP's precision-engineered fastener system. The ARP 454-2103 intake manifold bolt kit features high-strength chrome moly construction rated at 170,000 psi tensile strength, designed to maintain consistent clamping force under extreme operating conditions.

Key Features:

• 12-point head design for improved wrench engagement and reduced fastener rounding
• Black oxide finish chrome moly steel construction for durability and corrosion resistance
• Wide underhead flange distributes load evenly across gasket surface
• Precision rolled threads prevent galling and ensure consistent torque values
• Companion washers included for optimal load distribution
• CNC machined to aerospace tolerances for superior thread engagement
• NASCAR-spec design includes one drilled head bolt for tech inspection sealing

ARP fasteners are precision-machined to provide optimum sealing of intake manifold gasket surfaces, eliminating vacuum leaks and ensuring proper engine performance. The generous flange head design and included hardened washers work together to prevent gasket crushing while maintaining even pressure distribution across the entire sealing surface.
