Shatter the restrictive, necked-down factory induction bottlenecks on your GM diesel engine with our high-velocity aftermarket intake air horns. Engineered to dramatically increase volumetric efficiency, these smooth-flowing intake tubes maximize fresh air delivery directly into your turbocharger compressor inlet housing. This collection features heavy-duty mandrel-bent aluminum and cast construction induction horns equipped with integrated surge guards, precision-machined O-ring sealing flanges, and accessory ports for monitoring sensors. Swapping out your stock plastic or cast tracking lines on 6.6L L5P, LML, or LBZ platforms drops turbocharger spool times, lowers exhaust gas temperatures (EGTs) on heavy towing grades, and straightens out internal induction turbulence to support true high-airflow competition or street performance tuning curves cleanly.
