Looking for a solid ram rho intake setup is probably one of the first things on your mind if you've just parked that high-output Hurricane-powered beast in your driveway. Let's be honest, while the RHO is an absolute unit straight from the factory, there's always that little voice in the back of your head saying it could be just a little bit better. Usually, that voice is right, especially when we're talking about how a twin-turbo straight-six breathes.
The transition from the legendary TRX V8 to the new RHO and its 3.0-liter Hurricane engine has stirred up plenty of debate. But if you've actually driven the RHO, you know it's no slouch. It's pushing out 540 horsepower and 521 lb-ft of torque. However, because it relies on two turbos to do the heavy lifting, it's incredibly sensitive to airflow. That's where a high-quality intake comes into play. It's not just about chasing a few extra ponies; it's about making the truck feel more alive and responsive when you mash the pedal.
The Hurricane Engine and Airflow Dynamics
The heart of the Ram RHO is that high-output (H.O.) Hurricane engine. Unlike the old HEMI, which was all about displacement and naturally aspirated grunt, the Hurricane is a precision instrument. Turbos work by compressing air, and the easier it is for them to pull that air in, the more efficiently they can do their job.
When you stick with the stock ram rho intake system, you're dealing with a setup designed by engineers who have to balance performance with things like "drive-by noise regulations" and "service intervals for the average driver." These stock boxes are often heavy, made of thick plastic to muffled sound, and use paper filters that get clogged up pretty quickly. If you want those turbos to spool faster and hold boost more effectively, you've got to open up the airway.
Think of it like trying to run a marathon while breathing through a straw. You can do it, but you're working way harder than you need to. Swapping to a high-flow intake is like ditching the straw for a snorkel. It doesn't just help at the top end of the RPM range; it helps the engine breathe better across the entire power band.
What Makes an Aftermarket Intake Worth It?
You might be wondering if it's really worth spending a few hundred bucks on a plastic tube and a fancy filter. Well, it depends on what you're looking for. If you're expecting 100 extra horsepower, you're going to be disappointed. But if you want a more "connected" feel to the truck, it's one of the best bang-for-your-buck mods you can do.
Hearing Those Turbos Work
This is the big one for a lot of RHO owners. The stock intake is almost too quiet. Ram did a great job making the cabin a nice place to be, but for some of us, we want to hear what we paid for. A performance ram rho intake usually removes the baffles and resonators that the factory installs to silence the engine.
Once you swap it out, you'll start hearing the turbos whistle as they spool up. When you let off the gas, you'll get that satisfying "whoosh" of air. It transforms the driving experience from feeling like a luxury SUV to feeling like the desert-running trophy truck it's meant to be. It's a purely emotional upgrade, sure, but it puts a smile on your face every time you merge onto the highway.
Throttle Response Gains
Because the RHO is turbocharged, there's always going to be a tiny bit of lag compared to a big V8. However, a better intake can help minimize that delay. By reducing the vacuum restriction in the intake tract, the turbos don't have to work as hard to get up to speed. This results in a crisper throttle response. You'll notice the truck feels a bit "lighter on its feet" when you're navigating traffic or trying to power out of a corner on a dirt trail.
Open vs. Closed Air Box Designs
When you start shopping for a ram rho intake, you're going to see two main styles: open-box and closed-box. This is where the internet forums usually start arguing, but it's actually pretty simple once you break it down.
Open air boxes look cool and sound even better. They leave the filter exposed (sometimes with a heat shield) so you get the maximum amount of induction noise. The downside? They can suck in hot air from the engine bay if the shielding isn't great. On a truck like the RHO, which already generates a lot of heat under the hood due to the twin turbos, heat soak can be a real performance killer.
Closed air boxes are usually the way to go for a truck that's actually going to see off-road use. These systems keep the filter encased in a plastic or carbon fiber box that draws air from outside the engine bay (usually through the grille or hood scoop). This keeps the Intake Air Temperatures (IATs) lower, which is crucial for maintaining power during long drives or heavy-footed trail sessions. Most of the top-tier brands focusing on the Ram RHO are leaning toward closed-box designs because they want to maintain that "Ram Tough" reliability.
Dealing with Heat Soak
Speaking of heat, we need to talk about how it affects your RHO. Turbocharged engines are basically heat pumps. The hotter the air going into the engine, the less oxygen it contains, and the less power you make. The ECU (the truck's brain) is very smart; if it sees the air getting too hot, it'll pull back the timing and boost to protect the engine.
A well-designed ram rho intake will use materials that don't soak up heat as easily as the stock plastic. Some high-end kits even use XLPE (cross-linked polyethylene) which is great at resisting the high temperatures found under the hood of a performance truck. By keeping the air charge cool, you ensure that your 540 horses are actually available when you need them, rather than being "neutered" by the computer because the engine is sweating.
Is It a Difficult Install?
If you're worried about spending a whole weekend in the garage with a pile of tools you don't know how to use, don't be. Installing a ram rho intake is usually one of the easiest DIY projects you can tackle. Most kits are designed to be "bolt-on," meaning they use the factory mounting points and don't require any cutting or drilling.
You can usually get the job done in about 30 to 60 minutes with a basic socket set and a couple of screwdrivers. The hardest part is usually just wiggling the factory rubber bellows off the turbo inlets. Once the old stuff is out, the new system usually drops right in. It's a great way to get to know your truck a little better without the risk of breaking something expensive.
Maintenance and Longevity
One of the hidden benefits of an aftermarket intake is the filter itself. Factory paper filters are "one and done"—once they're dirty, you throw them away. Most performance intakes come with either a dry synthetic filter or an oiled cotton gauze filter. These are often washable and reusable.
If you're taking your RHO out into the dust and sand (which, let's be real, you should be), you're going to get that filter dirty fast. Being able to pull the filter off, give it a quick cleaning, and pop it back in saves you money in the long run. Plus, these filters generally have a much larger surface area than the stock ones, so they can hold more dirt before they start to restrict airflow.
Final Thoughts on the Upgrade
At the end of the day, the Ram RHO is a phenomenal piece of engineering. It's fast, it's capable, and it's arguably more tech-forward than the TRX ever was. But like any mass-produced vehicle, there's room for improvement.
Upgrading your ram rho intake is about more than just a spec sheet. It's about hearing the turbos sing, feeling a bit more snap when you hit the gas, and knowing your engine is getting the cleanest, coolest air possible. Whether you're hitting the dunes or just want your daily commute to sound a bit more aggressive, it's a modification that pays off every time you turn the key. Just make sure you pick a kit that matches how you plan to use the truck—prioritize filtration and heat management if you're an off-roader, or go for that open-box sound if you're a street king. Either way, your Hurricane engine will thank you for it.
