2017-2025 F-150 3.5L Ecoboost Inconel Manifold Hardware Kit (A0141A)

The Full-Race Ford F-150 3.5L EcoBoost Inconel Exhaust Manifold Stud Kit is the ultimate solution for preventing the common and costly exhaust leaks associated with the OEM manifold hardware. Over time, the high heat and corrosion present in the exhaust system cause factory hardware to weaken, stretch, and loosen. Constructed of A286 Inconel Alloy, a non-magnetic, high nickel alloy originally developed for jet engine applications, this hardware offers superior temperature and corrosion resistance to ensure your manifolds remain sealed and leak-free under all conditions.

Features

• Constructed from A286 Inconel Alloy, an aerospace-grade material known for extreme temperature and corrosion resistance.
• Studs are made from M8 alloy with a yield strength of 105ksi.
• Prevents common exhaust leaks caused by OEM hardware weakening and corrosion under high heat.
• Maintains superior resistance to corrosion and thermal expansion compared to standard steel hardware.
• Each kit includes 16 studs and nuts for a complete installation on both manifolds.

Notes

• The high nickel content in Inconel is what gives it its superior resistance to corrosion and high temperatures.
• For proper installation, studs should be torqued to 8.8 lb-ft (12 Nm) into the cylinder head.
• Final torque specification for the nuts is 18 lb-ft.
