BBF S/S Intake Bolt Kit 6pt.

The ARP BBF S/S Intake Bolt Kit 6pt is a premium fastening solution engineered for Ford FE-Series engines requiring factory-grade or performance-level intake manifold security. As an experienced mechanic, you know that intake manifold bolts endure thermal cycling, vibration, and pressure stress—stock fasteners often loosen or fail under sustained boost or high-RPM operation. This stainless steel, 6-point head kit replaces OEM bolts with aerospace-grade fasteners that maintain clamping force and resist corrosion in harsh engine bay environments.

Constructed from corrosion-resistant stainless steel with a polished hex head finish, these fasteners deliver superior tensile strength and elastic properties compared to standard cast-iron hardware. The 6-point design distributes load more evenly across the bolt head and socket, reducing the risk of stripped fasteners or rounded corners—critical when working on vintage or rebuilt FE-block engines where bolt access is often tight. ARP's proprietary manufacturing and testing protocols ensure consistent hardness, concentricity, and thread quality that outperform commodity alternatives and OEM replacements.

This kit is ideal for street builds, restorations, and performance modifications on 427, 428, and 455 cubic-inch FE platforms. Whether you're sealing a stock intake manifold or upgrading to an aluminum performer unit, these bolts ensure a leak-free, vibration-resistant joint that holds through thousands of heat cycles. Installation is straightforward using standard metric or SAE tools, and the polished stainless finish resists discoloration and corrosion, maintaining a professional appearance under the hood for decades.
