Please note that this manifold will only be available for a limited time at this price. We aim to provide customers with a fair opportunity to purchase for those who have been waiting for years but are not willing to pay the inflated prices of other sellers. Some have attempted to exploit the market due to the limited availability of the product, selling this manifold for between $4000 and $5000. Because of the stringent high-quality control of the manufacturer, there is only a limited supply available. We are selling them one at a time to ensure that vendors who have been exploiting the boss 429 market cannot prevent other customers from purchasing at a fair price by purchasing our entire inventory at this reduced price. Remember, this price will not last long nor will be availability!


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 sandblasting to maintain the OE Ford 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 important, this is the same manifold that you will find elsewhere for between $4,000-$5,000, without the huge markup.


Included in the package:

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

1) Set of Premium Washers

1) Water Bypass Tube
