Skeletonized, print-ready head flange STL for custom welded intake manifold fabrication.

This is a professional-grade STL file designed specifically for metal additive manufacturing and post-print welding. The geometry is optimized for cost-effective printing, controlled distortion, and DIY or professional intake builds.

This is a digital product only — no physical parts included.

Key Features

• Ford Coyote-specific head flange

• Single injector configuration

• 14 mm injector bores

• Compatible with OEM injector O-rings

• Skeleton flange design to reduce metal print cost

• 2.5 mm runner weld wall thickness for reliable TIG welding

• Gasket-matched port geometry

• Designed for welded, fixtureless assemblies when proper sequencing is followed

Design Intent

This flange is intended for custom intake manifold construction, not bolt-on replacement parts.

The design prioritizes:

• Efficient metal printing (SLM / DMLS / Binder Jet + sinter)

• Weld stability and reduced flange warping

• Clean runner attachment geometry

• Modular integration with plenum and throttle body systems

This is the same design logic used in high-end custom intake fabrication — made available for builders who want to manage their own printing and QC.

Runner Compatibility

This flange is suitable for DIY builds using:

• Ross Machine Racing oval runners, or

• G1Pro printed runner STL packs (sold separately)

Builders may mix and match based on fabrication preference and budget.

File Details

• Format: STL only

• Resolution: High-poly, print-accurate mesh

• Use: Metal printing or polymer prototyping

Editable CAD formats (STEP / SolidWorks / Inventor) are not included.

Who This Is For

✔ Experienced fabricators
✔ Builders printing their own intake components
✔ Shops producing custom or small-batch manifolds
✔ Users familiar with welding and post-processing

Who This Is Not For

✖ Beginners looking for plug-and-play parts
✖ Anyone expecting editable CAD files
✖ Digital file resellers or redistributors

Important Notes

• Digital product only — no physical part included

• Printing, material selection, machining, and welding are the buyer’s responsibility

• No support provided for print settings or welding technique

• Due to the nature of digital files, all sales are final
