GT40 5.8L Windsor Lower Intake Manifold

The Ford RF-F3TE-9K461-EA is a GT40 lower intake manifold, originally found on the 1993-1995 Ford Lightning trucks equipped with the 351 (5.8L) Windsor V8 engine. This part is identifiable by its part number and is physically wider than intake manifolds designed for the 302 engine. It is crucial to note that this lower intake manifold is specifically designed for 351 Windsor engines and will not fit 302 applications. Proper fitment depends on having the correct engine displacement. The GT40 intake system, including this lower manifold, was part of a performance upgrade package for the Lightning, which also included GT40-type cylinder heads, tubular "tuned" manifolds, and other enhancements to boost performance.
