  Ignition Coil Bolt, Stud Assembly Fastener

• Description:

  This is a genuine Ford ignition coil bolt, catalogued for the 6.2L V8 used in the F-250 and F-350 Super Duty across the 11-19 window and also appearing in related intake and ignition diagrams for other Ford applications. It is the threaded fastener that secures the coil-on-plug ignition coil to the valve cover or cylinder head boss, holding the coil down over the spark plug so the boot stays seated and the high-tension connection remains tight. A correctly torqued coil bolt is important to keeping the coil from lifting under engine vibration, which would otherwise cause an intermittent misfire. Owners replace this bolt during ignition coil or spark plug service, when the original has corroded or stripped, or when a misfire has been traced to a loose or backed-out coil hold-down. Because the coils sit in an exposed under-cover location, the bolts are commonly renewed as a set during a tune-up so every coil clamps evenly. Manufactured to Ford specifications, it matches the original thread size and head so it installs in the original location without modification. Always confirm the threaded boss is clean before installation, seat the coil squarely so the boot engages the plug fully, and torque to the value given in the applicable ignition service section. Inspect each coil boot and the bolt boss for oil or corrosion while the hardware is out, since a fouled seat will let the coil work loose again.
