Limited Run New Blue Thunder Four Barrel Dual Plane Intake Manifold with Ford Casting Numbers.

The C9AE-9425-D manifold you see in this listing is machined to original Ford prints, which means it will fit your Boss Nine engine compartment configuration i.e. hood clearance.

This casting has been sandblasted to better match the appearance of the original appearance, preventing color changes and surface flash rust commonly seen in other aftermarket manifolds treated with iron media during shot peening.

Every surface of this manifold has been CNC machined to precision, with a tolerance of .0023 of an inch, ensuring perfect fitment. Utilizing proprietary cutters, the manifold boasts smooth, clean surfaces, allowing for easy removal and installation during tuning without damaging the gasket.

A standout feature of this manifold is its rigorous pressure testing. The port locations are designed for immediate use on your engine. In addition to using aircraft-grade aluminum in the casting process, Blue Thunder goes the extra mile by pressure testing each manifold, guaranteeing quality and saving time for serious engine builders who would otherwise face potential leaks.

This manifold is meticulously detailed, reflecting the same quality seen in the provided images. We refrain from showcasing items that do not accurately represent the product you will receive.

Unlike other manufacturers who use recycled casting materials, skip pressure testing, and employ inferior cutters, Blue Thunder sets a standard of excellence. Even when we occasionally resort to other aftermarket Big Block Ford manifolds due to Blue Thunder's availability, we consistently find Blue Thunder's products to be superior. If you're tired of dealing with poorly crafted manifolds featuring obscure branding, rough castings, misaligned ports, and leaks, then this manifold is the ideal solution for you.

Most importantly, this is the same manifold you've seen elsewhere being sold for between $4,000 and $5,000 (without the hefty markup). This manifold is guaranteed to be authentic and manufactured in the United States of America. We invest extra to ensure our manifolds come with a certificate of authenticity, especially given the high value of this manifold. We empathize with the frustration experienced in the automotive community when purchasing an item believed to be made in the USA, only to later discover deception through misleading narratives like "assembled in the United States of America" or "stocked in the United States of America". We strictly offer domestically manufactured products and do not deal in inferior foreign merchandise.

Included in the package:

1) CNC Machined Blue Thunder Four Barrel Dual Plane Intake Manifold

1) Set of Premium Washers

1) Water Bypass Tube
