Description
Overview
The iFJF Stainless Exhaust Manifold Stud Nuts Kit is a complete replacement solution for the rust-prone OEM studs on Ford 4.6L and 5.4L V8 engines. These modular engines are notorious for manifold stud failure — causing exhaust leaks, ticking noises, and reduced performance. Our stainless steel kit provides a permanent fix that won't corrode or snap like factory steel studs.

Why Choose iFJF?
Ford factory exhaust manifold studs are made of carbon steel that rusts and snaps over time — especially in northern states with road salt. Our 304 stainless steel studs and nuts are the permanent solution. At a fraction of dealer prices, you get a complete kit that covers both manifolds and lasts the life of your engine.
FAQ
Q: Will this fit my 2006 F-150 5.4L?
A: Yes. This kit fits all 4.6L and 5.4L Ford Modular V8 engines, including the 2004-2008 F-150 with the 5.4L 3V Triton.
Q: How many studs are in the kit?
A: The kit includes the full set of studs, nuts, and washers for both driver and passenger side exhaust manifolds — typically 16 studs for V8 applications.
Q: Do I need to remove the manifold to install these?
A: Yes. The manifold must be removed to properly extract broken OEM studs and install new ones. This is an intermediate-level job requiring patience and penetrating oil.
Q: Are these better than OEM Ford studs?
A: Yes. OEM Ford studs are carbon steel — they will eventually rust and break again. Our 304 stainless steel studs are corrosion-proof.
Q: What are the symptoms of bad manifold studs?
A: Ticking noise on cold start that goes away when warm, exhaust smell in cabin, decreased fuel economy, and visible soot around manifold flange.
