NX Jets for the 2014‑up GM 5.3L plate system are CNC‑machined to ±.0005 tolerance and feature a contoured inlet with a multi‑stepped outlet to reduce turbulence and restriction. That contouring helped NX jets outflow competing jets by 35% in testing using identical nominal sizes, providing smoother, higher flow through the same orifice for fine‑tuned nitrous metering on GM 5.3L applications.
