This dual-plenum Sniper EFI fabricated intake manifold splits incoming air into two tapered plenums, one per cylinder bank, for better airflow distribution and increased velocity to each runner. Finished in black for a stealthy look, it uses extended 12.75 inch runners to build strong low-end torque for GM LS1/LS2/LS6 engines with a 102mm throttle bore.
