FITMENT
- 2003–2007 5.9L Dodge Ram 2500 3500 24V Cummins Turbo Diesel.
- Does NOT fit 1994–1998 12V engines, 1998.5–2002 24V engines, or 2007.5+ 6.7L Cummins engines.
DESCRIPTION
Product Overview
- Choked factory intake geometry holds back the true performance potential of your 3rd Gen 5.9L 24V Cummins. The tight, restrictive bends in the stock intake elbow restrict air volume and slow down charge-air velocity, leading to sluggish turbo response when pulling heavy loads or accelerating under boost.
- Upgrade to this Mandrel-Bent Aluminum Intake Elbow to open up your engine's intake tract. Its high-flow design maximizes air volume and delivers a smooth transition into the manifold for faster spool times, crisper throttle feel, and lower intake restriction. Plus, built-in NPT ports make adding boost gauges or performance accessories fast and easy.
Key Features
- Rugged 6061-T6 aluminum construction featuring TIG-welded tubing and CNC-machined mounting flanges for a leak-free seal under high boost pressure
- Replaces the restrictive OEM cast horn with a smooth mandrel-bent pipe that maximizes airflow efficiency into the intake manifold
- Sharpens turbo response by smoothing intake airflow transitions, reducing lag and improving drivability under load
- Retains the factory grid heater flange and bolts up using the included gasket and hardware — no turbo, manifold, or up-pipe removal needed
- Designed to support improved throttle response and breathing during towing and high-boost conditions
FAQ
Q: What advantages does this have over the OEM cast intake horn?
A: The larger 3.5" smooth-radius design eliminates the sharp bends and uneven cross-sections of the factory cast horn. This reduces airflow restriction, sharpens throttle response, and supports better engine breathing whether you’re towing heavy or running a performance tune.
Q: What can I use the two 1/8" NPT ports for?
A: They’re pre-tapped for easy installation of boost gauges, pressure sensors, temperature probes, or water-methanol injection nozzles. Any ports you’re not using seal up completely with the included brass plugs.
Q: Do I need to delete or relocate the factory grid heater?
A: Not at all. This intake elbow retains the factory grid heater flange and installs in the stock location using the included gasket and mounting hardware. Your cold-start grid heater stays fully operational.
Q: Will this fit if I’ve already upgraded my turbo?
A: Yes. It connects to the intake manifold side, so it works with most stock-location turbo upgrades as long as the intake horn mounting surface hasn’t been modified.
