• Description:

  The W704474-S437 is a genuine Ford stud built on the HT1 base, used to retain the exhaust manifold with integrated catalytic converter to the cylinder head. Dealer catalogs carry it under the dominant name Manifold With Converter Stud in the exhaust manifolds and headers section; it is the current service number, listed as a replacement for the earlier W704474-S309, and is paired with the W708176-S437 nut. Ford specifies that this stud cannot be reused or reinstalled, so it is a single-use fastener that should be replaced with a new one whenever the joint is disturbed. Documented sample applications where this exact service number is cataloged include the Ford Bronco, Explorer and Ranger and the Lincoln Continental, MKX and Zephyr, along with the Mercury Mariner and Milan; treat those as representative examples rather than a complete vehicle list, because Ford reuses one manifold stud across related engines and model years and does not publish a single finite fitment chart for it. A manifold stud threads into the head and gives the manifold flange a fixed post to clamp against, holding the joint sealed through extreme heat and thermal cycling. When one is corroded, stretched, broken or seized, the manifold can leak exhaust, tick on cold start, or break loose. Because the suffix code denotes a specific thread, length and material, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.
