Fit and finish as expected

Removing the OEM block was the hard part - you need all the tricks you know about loosening bolts to get it out and having a MIG welder really helps to weld the new bolts to the studs and back them!. The installation was successful with an extra set of hands. Install and finish where as well as expected.

Pros
  • Manifold
Cons
  • Secret

Saved me time and money

Great piece of cast iron header. Installation was painful but it fit my 98 XL f150 snugly. Couldn't be happier because now I have a great sounding exhaust. Just understand that the bold print that comes with this kit isn't for the head studs, it's for the flange on the donut that goes to the pipes that go to the catalytic converter. You must try to save your pins or buy new ones at the hardware store.

Pros
  • Automotive
Cons
  • Long wait

False advertising, wrong application and incomplete kit.

Product display says gasket and 4 studs. The first order received only had two studs and NO spacers. Also, the studs are M10, not M8 as required for the 4.6 liter Ford engine. The 5.4L uses M10 bolts but this kit is listed for both engines. The replacement order had the same two M10 studs but with a gasket. Also, the stud package was opened without a nut and without papers. Apparently this item was opened and returned and then mailed to me. If you can get this manifold or its sister manifold…

Pros
  • Replacement parts
Cons
  • Ok
