    Completely new design plenum and runners for optimized air/fuel distribution and power!

    Weiand recognized that todays engine technology has really advanced in our performance world since the Stealth series intake manifolds were originally designed some years ago. With larger stroker motors, more efficient cylinder head designs and aggresive cam profiles has brought about a need for an intake manifold capable of supporting these power houses.
    So Weiand wiped the work bench clean and started over.
    The newly redesigned Stealth dual plane intakes will nearly match a single plane manifold's peak horsepower number with a much fatter torque curve that is perfect for street and heavy duty/towing applications.

  • High rise, dual plane, design builds maximum torque and horsepower for street/strip applications
  • Square bore carburetor flange
  • permanent mold casting process for lighter, smoother, better looking and more consistent castings
  • Fully CNC machined for a perfect fit

    In addition, some of these manifolds feature Weiand's Everbright coating. Virtually maintenance-free, this polished finish is the product of vacuum metalizing technology and protective clearcoating...looks good, lasts long.
