K系列用 -6AN 中央進油「隱藏式」燃油軌套件

The machining on the fuel rail flanges is spot on, lined up perfectly with my K-series intake manifold without any binding. No more fighting with misaligned bolt holes like on my old setup.

Finally got my centerfeed setup dialed in and these rails made the whole routing much cleaner than the stock crossfeed mess. The -6AN ports are tapped perfectly, so the braided line went on without any cross-threading drama. Tucked look is exactly what I was after, and it’s holding pressure with zer

The billet rails lined up perfectly with my manifold ports, no binding at all. Using my existing -6AN fittings was a breeze, and the tucked profile really cleaned up the engine bay.
