Competition Use Only, Not Legal for Road Use

We are proud to introduce the Texas Speed & Performance Cathedral Sheet Metal Intake Manifold!  After lots of engine dyno testing on our SuperFlow 902 engine dyno, we have developed a quality design that offers excellent power gains vs. other sheet metal intake manifolds on the market.  Below are some of the features:
  • Bolt-In CNC Billet Aluminum Runners
  • Sheet Metal Intake Plenum
  • Accepts Up To 102mm Throttle Body
  • Includes Fuel Rails, -8 AN
  • Comes in Semi-Flat Black Powder coating
  • Thick Sheet Metal Combined With Billet CNC Runners For a Strong, Rigid Setup That Won't Distort Under Boost or Warp During Installation
  • Drilled to Accept Factory or Aftermarket Fuel Injectors
  • Uses Factory Intake-to-Head Gaskets
  • Perfect for Retrofit Applications
We use thick sheet metal for the intake plenum for maximum rigidity, so you will not have any issues with the intake manifold distorting under boost or warping during installation.  The intake runners are CNC billet aluminum and offer a smooth transition from the plenum into the runners.  This is a high-quality intake manifold that will complement any cathedral-headed engine combination.  It is an ideal choice for 400+ CID stroker engines and aggressive heads/cam packages.


*Please note that this intake manifold will NOT fit some vehicles with limited cowl or fire wall clearance. These vehicles may require the stepped version of our intake manifold to properly clear the firewall.
