The Ram TRX is a predator. With 702 horsepower screaming from a 6.2L Supercharged HEMI V8, it stands at the top of the food chain. But even a predator needs to breathe. The factory airbox is designed for the masses: it’s built to be quiet and compliant. If you want to unlock the full potential of that Hellcat powerplant, you need to ditch the restrictions.

A high-performance cold air intake (CAI) is the first modification any TRX owner should consider. It’s about more than just numbers on a dyno; it’s about throttle response, supercharger whine, and efficiency. In this shootout, we break down the heavy hitters: S&B Filters, aFe Power, and CPS.

Select your upgrade. Push your limits. Build a monster.

The Performance Breakdown: HP and Torque Gains

When you're chasing triple-digit speeds off-road or at the strip, every pony counts. Here is how the top contenders stack up in raw performance data.

S&B Filters: The Power King

If you want the absolute maximum horsepower gain from a bolt-on intake, S&B Filters takes the crown. Their engineering team didn’t just make a tube; they redesigned the entire induction path.

Why S&B Dominates

S&B utilizes a massive, nearly two-foot-long filter. The intake features a massive 4.125" x 6.75" oval inlet that minimizes restriction at high RPMs. On the dyno, the S&B system has shown a peak boost increase of over 1 psi compared to the stock configuration. In the world of supercharged engines, more boost equals more win.

Engineering Excellence

• Snap-In Lid: No screws, no hassle. The clear lid snaps into place, allowing for 5-second filter inspections.
• Premium Media: Choose between 8-layer cotton cleanable media or dry extendable media for those in dusty, high-desert environments.
• Airflow Path: Designed to maintain a seal against the hood, ensuring only cold, dense air enters the supercharger.

Shop with confidence knowing S&B is one of the most trusted names in the off-road performance world.

aFe Power: Precision Engineering

aFe Power (advanced FLOW engineering) has been the gold standard since 1999. They don't offer a "one size fits all" solution. Instead, they provide tiers of performance based on how you use your TRX.

The Track Series (Maximum Performance)

The Track Series is designed for the enthusiast who wants zero compromises. It features a lightweight aluminum tube and an open-element design that provides a 30% improvement in airflow. If you want to hear that supercharger scream under load, this is your choice.

The Momentum GT (Daily Driver Performance)

For those who live in harsher climates or use their TRX for heavy off-roading, the Momentum GT features a fully sealed housing. This protects the filter from heat soak and debris while still providing a massive 19 HP gain.

Filter Technology: Choose Your Weapon

• Pro 5R: 5-layer oiled media for maximum flow on the street and track.
• Pro DRY S: 3-layer oil-free media for easy maintenance.
• Pro-GUARD 7: 7-layer media designed for maximum filtration in heavy dust.

CPS: The Sound Machine

Let’s be honest: half the reason we buy a TRX is the sound. The CPS Cold Air Intake is widely recognized as the loudest intake on the market.

While its 15 WHP gain is slightly lower than S&B’s peak numbers, the sensory experience is unmatched. CPS focuses on harmonic resonance. Inside the cabin, with the windows up, you will hear the supercharger whine significantly more than with any other brand. Outside, the bypass valve and induction roar are aggressive and unmistakable.

CPS Highlights

• Acoustic Tuning: Engineered to amplify the 6.2L's natural supercharger whine.
• Premium Finish: Often available in custom powder-coated finishes to match your TRX's trim.
• Direct Fit: Minimalist design that installs in under 45 minutes with basic hand tools.

JMB Performance: The Heavy Hitter

For those who want a custom, "built not bought" look, JMB Performance offers a 5" TIG-welded aluminum intake. This is a massive pipe designed for trucks moving serious amounts of air: perfect if you plan on upgrading to a smaller pulley or a larger throttle body later. The heat shielding is top-tier, ensuring that the aluminum doesn't become a heat sink during long sessions in the dirt.

Technical Considerations: What to Look For

Before you select your intake, consider these three critical factors:

1. Filtration vs. Flow

If you are racing on the street, high-flow (oiled) filters like the aFe Pro 5R are ideal. If you are hitting the trails in Baja, you need maximum filtration (dry or multi-layer) to protect your engine from fine silt.

2. Heat Soak

Plastic (rotomolded) housings, like those from S&B and aFe, typically handle engine bay heat better than metal tubes. However, metal tubes often provide a more aggressive sound profile.

3. Installation

Most of these systems are "bolt-on." You won't need to cut or weld anything. However, you will want a reliable set of tools.

The DTX Verdict: Which One Should You Buy?

At DTX Performance, we prioritize results. Here is our expert recommendation:

• For the Power Hungry: Choose S&B Filters. The 20-25 HP gain and the boost increase make it the undisputed performance leader for the price.
• For the Sound Junkie: Choose CPS. Nothing makes the Hellcat engine sound as menacing as this intake.
• For the Engineering Purist: Choose aFe Power. Their Momentum GT system is the best-engineered sealed intake on the market, offering a perfect balance of protection and power.
