Pontiac Intake Bolt Kit 12pt.

The Pontiac Intake Bolt Kit 12pt. by ARP is the go-to fastener upgrade for engine builders and Pontiac enthusiasts seeking OEM replacement or performance-level reliability. When factory intake bolts fail or loosen under heat and vibration, they compromise cylinder head sealing and risking coolant leaks, vacuum breaches, and catastrophic engine damage. This 12-point socket head design ensures superior clamping force and repeatability, making it essential for any serious engine assembly, rebuild, or high-output application.

ARP's 12-point bolts are manufactured to exacting standards, featuring a 12-point head geometry that distributes load more evenly than 6-point fasteners and minimizes wrench slip during installation. The kit includes all bolts required for Pontiac intake manifold mounting, precision-engineered to eliminate galling and ensure consistent preload across the cylinder head gasket surface. The 12-point design also allows faster wrench engagement, critical when working in tight engine bay spaces. Each bolt is individually inspected and calibrated for tensile strength, ensuring predictable behavior under thermal cycling and combustion pressures.

This kit is ideal for Pontiac builds ranging from stock restoration to modified big-block applications, from street machines to competition engines. Installation requires only an appropriately-sized 12-point socket and standard torque wrench; follow Pontiac factory specifications or consult engine builder guidelines for your specific block and head combination. Whether you're refreshing a tired 400 or assembling a fresh 455, upgrading to ARP fasteners eliminates the risk of intake gasket failure and simplifies future teardowns thanks to improved bolt reusability and reduced corrosion compared to OEM hardware.
