Unlock More Power With A True Racing Inspired Manifold

If you’re serious about squeezing more performance out of your Cummins, the Banks Big Hoss Intake Manifold is a game changer. Designed straight from Banks Racing development on the legendary Sidewinder Dakota, this manifold brings race-proven performance into your build. Whether you're chasing better throttle response, more usable power, or simply want to build your truck with parts that back it up on the track, the Big Hoss delivers. By improving airflow and distributing it more evenly across all cylinders, your engine breathes easier and works more efficiently. That means more power at the same boost, better combustion, and cleaner running. It’s also perfect for those looking to push limits at the track or dyno since it allows for porting modifications. This is not your average bolt-on upgrade, it’s an opportunity to take your truck’s power to the next level.

Engineered To Feed Power Where It Counts Most

The Banks 42747 Big Hoss Intake Manifold was designed to address one of the biggest bottlenecks in performance diesel tuning, air delivery. Built specifically for 2003 to 2007 5.9L Cummins engines, this manifold completely reworks airflow dynamics by delivering more volume and distributing it more uniformly to each cylinder. The improved design means combustion is more balanced across the engine, which results in greater efficiency and increased output. This system includes the intake manifold, boost hose, clamps, and all necessary relocation hardware for the dipstick tube and wire loom. One standout feature is that it supports porting of the intake ports, giving custom builders and racers more flexibility when dialing in their setups. It’s made for sanctioned racing use, so it’s clear this manifold isn’t just for looks, it’s built for purpose. Whether you’re optimizing air delivery for high horsepower builds or laying the foundation for serious performance upgrades, this system is built to handle it.
