This 100-piece Engine Inlet and Exhaust Manifold Stud and Nut Kit by Connect is designed for automotive technicians and DIY enthusiasts who perform engine maintenance on a wide range of global vehicle brands. It provides a comprehensive selection of M8 and M10 hardware essential for replacing studs that have sheared due to corrosion or thermal fatigue. While the kit covers the most common thread pitches and lengths, users should verify their specific vehicle's required stud length before installation, as incorrect sizing can lead to improper manifold seating.

Yes, the high-temperature capabilities of the included materials make them suitable for exhaust applications, including turbo flanges.
The kit covers most common M8 and M10 sizes used by major brands like Ford, Honda, BMW, and VAG, but you must verify your specific model's requirements.
Copper-flashed nuts help prevent seizing, while brass nuts offer superior resistance to corrosion in extreme temperature environments.
The M8 nuts use a 13mm hex, while the M10 nuts use 14mm and 17mm hex sizes depending on the material.
Use a hacksaw or a cut-off tool, and be sure to file the cut end smooth so the nut can be threaded on without damaging the threads.
Check the thread pitch (M8x1.25 or M10x1.5) to ensure a match and inspect the stud end for burrs caused by cutting.
Verify if the original threads in the block have been stripped during previous removal; a helicoil or thread repair may be required.
Before installing new studs, ensure the engine block or cylinder head threads are clean and free of debris using a thread chaser. When replacing existing studs, measure the original length accurately. If a stud in the kit is too long, cut it to the required size and deburr the end to ensure the nut threads on smoothly. When using the brass nuts, avoid overtightening as brass is softer than steel and can strip if the torque specification is exceeded. Always use a high-temperature anti-seize compound on the threads to further extend the life of the components.
