Alpha Performance 18 Injector R35 GT-R Carbon Fiber Intake Manifold




Introducing the new Alpha 18 injector (injectors not included) R35 GTR intake manifold! The Alpha R35 GT-R Carbon Fiber Intake Manifold has been painstakingly designed by AMS to be the most efficient and power producing GT-R intake manifold on the market.


  • Same Championship Winning Design as our 12 Injector Version
  • Capable of utilizing 18 Injectors (not included)
  • The most powerful VR38 intake manifold on the market
  • Show stopping design
  • Over 30% lighter than the leading cast intake manifold
  • Dowel pin aligned for smooth, continuous flow between upper and lower runners
  • Dual MAP sensor ports allow for monitoring bank to bank differences in boost pressure
  • Extra vacuum ports on plenums
  • Upgrading from a 12 injector to an 18 injector center section is an option


  • Alpha Performance R35 GT-R Big Bore Billet Throttle Bodies Available
  • AMS Throttle Body Adapters Required for Use with OEM Throttle Bodies
  • Custom Color Matching of Intake Runner Anodizing Available Upon Request   
  • Standard billet, Black, Blue, Gold, Purple, Red
  • CNC billet aluminum upper and lower section gasket
  • Throttle body and lower intake manifold gaskets
  • All necessary vacuum fittings and hardware

Product Notes:

  • Custom PCV routing would be needed if the owner wishes to retain its functionality
  • Alpha upper intercooler pipe adapter for current Alpha intercooler piping or full Alpha Induction Kit is required.
  • Injectors, injector wiring, and fuel lines are not included and must be custom designed and built.
  • While other fuel rail kits may work (stock rails are not compatible), AMS can only guarantee AMS Fuel Rails to be compatible with this intake manifold.
  • Custom color anodizing can add 2-4 weeks to build time.
  • As these motorsports grade carbon fiber parts are hand laid, slight imperfections or weave pattern variances can be expected.
