Eight ports for probes, injection, and monitoring, with plugs for unused ports
Includes gaskets, hardware, and couplers for a quick, hassle‑free install
Street legal in all 50 states with CARB EO D‑590‑7
The S&B 76-1004-1 Intake Elbow is built to perform on your 5.9L Cummins by replacing the restrictive OEM turbo inlet manifold with a larger, smoother‑flowing casting designed specifically to feed your charger the air it needs. CNC‑machined from 6061‑T6 aluminum and TIG‑welded for strength, this elbow stands up to high boost and heavy towing while looking right at home in a clean engine bay. By reducing inlet restriction, it promotes faster turbo spool‑up, improved throttle response, and reduced exhaust gas temperatures—especially noticeable when towing, tuned, or running larger tires.
Integrated NPT ports make this elbow a flexible upgrade platform for your Ram. With eight auxiliary ports available, you can easily add pyrometer probes, boost reference, nitrous or water‑meth nozzles, or pressure sensors, while the supplied plugs seal any unused ports for a leak‑free installation. Each kit comes complete with a graphite gasket, silicone hump coupler, T‑bolt clamps, and all necessary hardware so most owners can install it at home with basic hand tools. With CARB certification and “street legal in all US states” status, it’s a smart choice for daily drivers that still demand real performance gains.
S&B backs the 76-1004-1 Intake Elbow with a 5‑year product warranty, covering defects in materials and workmanship under normal use. According to S&B’s documentation, once the part has been installed it is typically not returnable, so dry‑fit and confirm fitment before final torque where possible and retain proof of purchase for any warranty claim. Follow the supplied torque specs (in‑lb) and use a 1/4‑inch drive ratchet to avoid over‑tightening the included fasteners.
These are common reasons owners upgrade or replace this component:
Higher than normal EGTs under load or towing due to intake restriction.
Sluggish turbo spool or lazy throttle response compared to similar setups.
Evidence of boost leaks or soot/oil around the factory elbow connections.
Cracked, corroded, or damaged OEM casting when running higher boost or age‑related wear.
Limited ports for sensors or injection, forcing “hack” solutions instead of clean plumbing.
(Actual diagnostic trouble codes are typically related to boost or airflow—such as under‑boost—when restriction or leaks are severe; specific codes vary by tune and sensor configuration.)
Q: Will this fit my 5.9L Cummins from 2003–2007?
A: Yes, this elbow is designed for 2003–2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins engine.
Q: Do I need tuning after installing this intake elbow?
A: No tuning is required; it’s a bolt‑on airflow upgrade, though tuned trucks can see even greater benefit from reduced restriction.
Q: Is it emissions legal in California?
A: Yes, the S&B 76-1004-1 carries CARB EO D‑590‑7 and is listed as street legal in all US states when installed on appropriate applications.
Q: What tools do I need to install it?
A: S&B’s instructions call for common hand tools including a 7/16" deep socket, 3/16" and 6 mm hex drives, a 1/4" drive ratchet, a torque wrench (inch‑pounds), and a gasket scraper or vacuum to clean the manifold surface.
Q: Does it come with the gaskets and couplers I need?
A: Yes, the kit includes a graphite manifold gasket, silicone hump coupler, T‑bolt clamps, and all necessary studs, bolts, and plugs for a complete install.
