3. **Remove the Spark Plug Wires**: Gently pull the spark plug wire off the spark plug. If it’s stuck, you can use pliers to wiggle it free. Be careful not to pull on the wire itself; pull on the boot (the rubber part).

4. **Clean the Area**: Before removing the spark plug, use a clean cloth to wipe away any dirt around the spark plug. this prevents dirt from falling into the engine when you remove the plug.

5. **Remove the Old Spark Plug**:
– Place the spark plug socket over the spark plug.
– Use the ratchet and extension to turn the socket counterclockwise. It may take some force to break it loose. Once it’s loose, you can unscrew it by hand.

7. **Install the New Spark Plug**:
– Apply a small amount of dielectric grease to the threads of the new spark plug (this helps with installation and future removal).
– Carefully screw the new spark plug into the hole by hand until it’s snug. Then, use the torque wrench to tighten it to the manufacturer’s specifications (found in your owner’s manual).

8. **Reattach the Spark Plug Wires**: Push the spark plug wire back onto the new spark plug until you hear a click. Make sure it’s securely in place.

A manifold stud is a crucial component in the assembly of an engine, primarily used to secure the intake or exhaust manifolds to the engine block. These studs are typically made of high-strength steel or alloy materials, designed to withstand the intense heat and pressure generated during engine operation. The manifold itself serves as a conduit for air or exhaust gases, and the stud plays a vital role in maintaining a tight seal between the manifold and the engine, ensuring optimal performance.

Manifold studs are usually threaded on both ends, with one end screwed into the engine block and the other end accommodating a nut or a washer to secure the manifold in place. this dual-thread design helps to distribute the clamping force evenly, minimizing the risk of warping or damaging the manifold or the engine block. During installation, proper torque specifications must be followed to prevent over-tightening, which could lead to stripping the threads or causing stress fractures.

Over time, manifold studs can be subjected to corrosion, especially in environments where road salt or moisture is prevalent. Regular inspection is essential, as a failing stud can lead to manifold leaks, resulting in performance issues, increased emissions, and potential engine damage. Therefore, understanding the role and maintenance of manifold studs is essential for anyone involved in automotive repair or performance enhancements.
