Nitrous Express Aluminum Annular Nozzle Bung

Nx STD (Straight Through Design) Nozzle bung feature a recessed chamber design which raises the nozzle tip out of the runner for maximum power gains. We have seen a 40hp gain on the Dyno, compared to not using a bung! These are an aluminum weld in design for use with 1/16thnpt STD / Annular nozzles.
