Kooks 1-5/8" x 2-1/2" stainless headers for the V8 3V Ford trucks — frees up the airflow restriction created by the factory cast manifolds without overcommitting on primary size. The 1-5/8" primary is matched to the 5.4L 3V's airflow needs, broadening the torque curve and opening up the top end. 16 gauge 304 stainless construction with a two-bolt flange collector for solid connection to the Y-pipe.
Fits 2009-2010 Ford F-150 and Raptor 5.4L 3V. Requires a Kooks Y-pipe with a 2-1/2" inlet (PN 13503100) to complete the connection. Round port, stock bolt pattern bolts directly to 5.4L 3V cylinder heads.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every Kooks header is welded by experienced fabricators in the same shop where the company's racing legacy was built. 304 stainless construction handles thermal cycling and salt-belt corrosion.
Includes gaskets and header bolts for installation. Pair with Kooks 5.4L Y-pipe (PN 13503100) downstream.
