GM GenV LT Lo-Ram Intake Manifold Kit

The GM GenV LT Lo-Ram Intake Manifold Kit (HLY300-718BK) from Holley is a high-performance fuel delivery system engineered for fifth-generation GM LT-series engines, delivering optimized airflow and fuel atomization for improved combustion efficiency. Designed for enthusiasts and professional builders who demand precision engine management, this complete kit eliminates the guesswork associated with aftermarket intake selection by integrating fuel rails and a purpose-built manifold geometry into one integrated assembly.

This aluminum Lo-Ram configuration features a 105 mm throttle body flange and comes finished in durable black powder coat, providing both corrosion resistance and a professional appearance under the hood. The Lo-Ram design positions fuel injectors closer to the combustion chamber than traditional high-rise manifolds, reducing fuel travel distance and improving response time—a critical advantage in competition and high-output applications. Included fuel rails are pre-contoured to minimize dead space and pressure loss, while the aluminum construction keeps overall engine weight low without compromising structural integrity.

This manifold kit is ideal for LT1, LT4, and other fifth-generation LT variants in trucks, performance cars, and custom builds where intake design directly impacts power delivery and drivability. Installation requires proper fuel system configuration and throttle body calibration; compatibility with existing fuel pressure regulators and return-line plumbing should be verified before purchase. Weighing 30.64 lbs and measuring 15.35 x 14.96 x 24.21 inches, it integrates seamlessly into most engine bay layouts while maintaining clearance for accessory drives and cooling lines.
