The Nitrous Express 4150 single‑entry crossbar nitrous plate is a billet crossbar design that replaces round spray bars to improve atomization and cylinder distribution. CNC machined to eliminate sagging or rotating spray bars, the crossbar plate promotes more consistent nitrous dispersion on 4150 4‑barrel mounting patterns and is supplied as the plate-only component for system builders.
