AMC Intake Bolt Kit 6pt.

The ARP Intake Bolt Kit 6pt (part number 114-2001) is a premium fastener upgrade designed for AMC V8 engine builds where OEM intake manifold bolts fall short of performance or reliability standards. This 12-piece chromoly bolt set with hex heads replaces factory hardware with stronger material capable of handling elevated boost pressures, aggressive engine tuning, and thermal cycling without galling or fatigue failure. ARP bolts are engineered to tighter tolerances than production fasteners and feature black oxide surface treatment for corrosion resistance in underhood environments.

Chromoly construction (4140 alloy steel) provides superior tensile strength compared to mild steel OEM bolts, reducing the risk of bolt stretch or failure under sustained higher cylinder pressures. The inclusion of washers ensures even load distribution across the manifold gasket face, critical for maintaining an effective seal on modified engines where gasket compression is essential. Hex head design allows straightforward installation with standard hex wrenches, and the black oxide finish resists corrosion from coolant exposure and engine bay moisture—a practical advantage over bare steel in long-term street and off-road service. These bolts are suited for both naturally aspirated high-compression builds and forced-induction applications where stock fasteners are inadequate.

This kit is essential for serious AMC V8 builders, engine rebuild shops, and enthusiasts running elevated boost or compression who demand fastener-grade reliability. Intake manifold bolt failure can lead to vacuum leaks, coolant seepage, and performance loss—outcomes prevented by upgrading to purpose-built ARP hardware. The kit's completeness (all 12 bolts and washers included) eliminates the need to source fasteners separately, streamlining the rebuild process and ensuring consistency across all mounting points.
