Furthermore, the OEM corrugated profile and step-downs disrupt laminar airflow across the dual mass air flow sensor probes. This boundary-layer separation causes erratic frequency readings, skewing short-term fuel trims and limiting boost ramp rates on the twin-turbocharged 4.4L platform under heavy load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a matched pair for dual-bank intake systems, these replacement housings are constructed from 6061 billet aluminum tubing featuring a consistent 3-inch (76mm) outer diameter and micro-finished, smooth inner bore walls.
