Coyote Plastic Pro

A complete Coyote intake manifold you print yourself, on a printer you already own. Not a jig, not a flange, not a piece of one. The whole manifold — lower plenums, tops, throttle body snout, fuel rails, rail stands and the head flange inserts. Eight print-ready STL files, fifteen printed pieces.

I have been building intake manifolds by hand since 2009. I would not have released this three years ago. Consumer printers are finally good enough, so I took a Coyote manifold and rebuilt it as a model a consumer machine can actually make.

Fits a 300mm cube printer

Sectioned and oriented to come off a 300 × 300 × 300mm bed as a minimum. Bigger machine, fewer joints.

The eight files

• Coyote front lower, stock port
• Coyote rear lower, stock port
• Coyote front top
• Coyote rear top
• Coyote front snout, 80mm throttle body
• Coyote fuel rail, −8ORB — print two
• Coyote rail stand — print four
• Coyote head flange inserts — print four

STL only. Print-ready, sectioned, oriented. Instant download at checkout — nothing ships and nothing waits.

The spec

• Plenum wall 7mm
• Runner wall 5mm
• 3× 3/8 NPT ports
• Stock port shape
• 80mm throttle body snout
• Big port version coming. And if you know your slicer, crank the wall count up and port it out yourself.

On material, and on boost

Run a filament rated for the heat. The material I specify carries a 200 hour rating at 125°C HDT. That is the part that matters and it is where most people get this wrong.

Straight talk on pressure: the one time I bonded PA6-CF with an even smaller bond cross-section than this design has, it held 80 psi. So with proper prep and a proper bond on a far friendlier material, I have no doubt it handles what your application asks of it. That is a bench result on a related part, not a dyno sheet on this one. I will tell you what I know and let you judge the rest.

Who this is for

The builder who wants a real manifold, has a printer, and has patience. Print it, bond it, port it, run it.

Licence — Shop Use

Print as many copies as you like for your own vehicles or for customer builds in your own shop. You may not share or resell the files, or produce manifolds from them for sale to third parties. Print-and-sell licences available — ask.

Drawn by James Goertz, G1Pro — building intake manifolds by hand since 2009, and the only shop in this business with a published price and a third-party dyno sheet on the site.
