The Edelbrock Pro‑Flo XT LS2 EFI intake manifold (as‑cast) for GM LS2 applications uses a large plenum and tapered runners to broaden the torque band and increase peak power—approximately 30 horsepower over a stock LS6 at 6,500 rpm. It features a 90mm throttle opening, 2.75" port exit height, and accepts GM 90mm or Edelbrock throttle bodies; compatible fuel rail kits are available separately.
