The Blueprint 392 Intake Manifold is one of the most popular intake manifold upgrades available for Gen 3 HEMI enthusiasts looking to improve airflow, increase horsepower, and enhance overall engine performance. Designed around the high-flow characteristics of the factory 6.4L (392) HEMI intake, this manifold provides exceptional airflow while maintaining excellent street manners and drivability. Whether you’re upgrading a 5.7L HEMI, refreshing your existing 6.4L combination, or building a complete naturally aspirated performance package, the Blueprint 392 Intake Manifold delivers the airflow needed to support impressive power gains throughout the RPM range.
Compared to the factory 5.7L intake manifold, the 392-style design offers significantly improved airflow characteristics through larger runners and an optimized plenum configuration. This allows the engine to breathe more efficiently, resulting in stronger mid-range torque, improved throttle response, and increased horsepower when combined with supporting modifications such as performance camshafts, long tube headers, custom tuning, upgraded throttle bodies, and cold air intake systems. The Blueprint manifold has become a favorite among Gen 3 HEMI builders because it offers OEM-style drivability while supporting substantially more airflow than the standard truck and early car intake manifolds.
This intake manifold is an excellent choice for naturally aspirated street builds, drag racing combinations, autocross vehicles, and daily-driven performance cars. Many 5.7L HEMI owners perform the popular 392 intake manifold swap because of its proven ability to unlock additional performance while retaining factory reliability. When paired with a proper ECU calibration, upgraded fuel injectors where required, and quality supporting components, the Blueprint 392 Intake Manifold becomes a key part of a balanced performance package capable of delivering noticeable gains across the entire powerband.
Manufactured with durability and precision in mind, the Blueprint 392 Intake Manifold is engineered for excellent fitment on compatible Gen 3 HEMI applications. Its lightweight composite construction helps reduce engine weight while minimizing heat transfer compared to traditional aluminum intake manifolds. Cooler intake air temperatures contribute to improved combustion efficiency and consistent performance during spirited driving, making this manifold equally at home on the street or at the drag strip.
At Dusterhoff Racing, we’ve used the Blueprint 392 Intake Manifold in countless customer builds ranging from mild bolt-on combinations to fully built naturally aspirated engines exceeding 500 wheel horsepower. It pairs exceptionally well with our custom camshaft packages, remote tuning services, power packages, larger throttle bodies, and cold air intake systems to maximize the performance potential of your Gen 3 HEMI. For additional intake upgrades, throttle bodies, installation hardware, and supporting performance components, browse our Intake Manifolds & Intake Components category to complete your build.
**This intake needs to be run with an aftermarket camshaft to show gains and take advantage of it’s higher rpm range.**
Includes:
Aluminum “BluePrint” EFI Intake High Flow Fuel Rails with Mounting Hardware MAP Sensor Provision on Plenum Intake Gaskets & Hardware Dual Throttle Body Pattern (Hemi and LS options) O-Ring for Throttle Body Throttle Body Bolts
When you run this intake manifold on a 6.4L car you have to swap over to the 5.7L JLT cold air intake.
