The Cadillac CTS-V Gen 3 is a masterpiece of American engineering. Under the hood lies the LT4: a supercharged 6.2L V8 capable of 640 horsepower and 630 lb-ft of torque. It is a beast, but even beasts need to breathe.
From the factory, your CTS-V is stifled. The stock airbox is designed for silence and mass production, not peak performance. It creates a massive bottleneck that limits the efficiency of your supercharger. If you want to push your vehicle further, the first move is clear: upgrade the intake.
At DTX Performance, we focus on modern muscle. We don't deal in fluff. We deal in power. Here is the definitive guide to the best CTS-V cold air intake systems for the Gen 3 platform.
The LT4 Airflow Problem
The LT4 supercharger moves a staggering amount of air. To generate boost, it must pull that air through the intake tract. The factory system uses restrictive filters and accordion-style tubes that create turbulence and heat soak.
By installing a high-performance cold air intake, you reduce pressure drop before the supercharger. This allows the blower to work less to produce the same amount of boost, resulting in lower Intake Air Temperatures (IATs) and immediate horsepower gains.
Build for precision. Select for power. Shop with confidence.
aFe Power Momentum GT: The Maximum Flow King
If you are looking for the highest-performing "no-tune" intake on the market, the aFe Momentum GT is the undisputed heavy hitter. This system is engineered specifically for the 2016–2019 CTS-V3.
Performance Breakdown:
- Design: Features a massive, 360-degree radial flow air filter housed in a sealed, one-piece rotomolded housing.
- Flow: Outflows the factory intake by nearly 20%, ensuring the LT4 never starves for air.
- Gains: Real-world testing shows gains of +12–15 RWHP on a stock tune. With a pulley and tune, those numbers jump significantly.
- Versatility: Available with the Pro 5R (oiled) filter for maximum flow or the Pro DRY S for maximum convenience.
The Momentum GT's unique filter-to-housing interface allows for the largest filter possible, which translates to more surface area and less restriction. It’s a sleek, modern solution for the serious enthusiast.
Airaid MXP Series: The Reliable Workhorse
For those who want a proven, OE-quality fit with consistent performance, the Airaid MXP Series (Part #250-334) is the industry standard. Airaid has been a staple in the CTS-V community for a reason: it works.
Why Choose Airaid?
- Sealed Cold Air Box: Replaces the entire factory airbox, maintaining a sealed environment to keep hot engine bay air out.
- Construction: Uses a high-density polyethylene intake tube designed to maintain a smooth, laminar flow into the throttle body.
- Simple Install: Bolt-on power in under an hour. No cutting, no drilling, no nonsense.
- Sound: Unlocks the hidden supercharger whine that Cadillac engineers tried to hide.
Expect a solid +8–12 HP gain on an otherwise stock car. It’s a professional-grade upgrade that prioritizes filtration without sacrificing the aggressive sound your V deserves.
New Era Performance: The Enthusiast’s Secret
For the CTS-V owner who plans on going big: think ported blowers, smaller pulleys, and custom tuning: New Era Performance offers systems that lean toward the "maximum volume" end of the spectrum.
New Era intakes are often the choice for racers who want the shortest, straightest path possible for airflow. While some of their configurations may require a tune to reach full potential, the reward is a throttle response that feels telepathic.
Key Advantages:
- Aggressive Intake Note: This is the loudest intake option, providing a raw, visceral supercharger scream under WOT.
- High-Volume Capacity: Designed to support builds pushing well over 700 RWHP.
- Track Focused: Prioritizes raw airflow and weight reduction.
Precision Engineering: HP, Torque, and Sound
Upgrading your CTS-V performance parts isn't just about a number on a dyno. It's about the experience.
- Throttle Response: Eliminating the factory "bog" makes the car feel lighter and more responsive in traffic.
- Efficiency: Lowering the effort required by the supercharger improves the overall efficiency of the LT4.
- Aesthetics: A high-quality intake from aFe or Airaid transforms your engine bay from "standard luxury" to "modern muscle."
Select Your Build. Push Further.
The CTS-V is a legend. Don't let a plastic factory box hold it back. Whether you choose the massive flow of the aFe Momentum GT, the refined reliability of the Airaid MXP, or the aggressive nature of New Era, you are making a statement.
At DTX Performance, we provide the best selection of auto parts for modern muscle. We promise to only send you good things: high-performance parts that actually deliver.

FAQ: CTS-V Cold Air Intakes
Q: Do I need a tune for a cold air intake on my Gen 3 CTS-V? A: Most systems like the aFe Momentum GT and Airaid MXP are designed to work perfectly with the factory ECU calibration. However, to maximize the gains: especially if you add other parts like headers: a professional tune is always recommended.
Q: Will a CAI void my Cadillac warranty? A: Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you have an aftermarket part. They must prove the part caused a specific failure. Many owners find these intakes to be a safe, reliable upgrade.
Q: Which filter is better: Oiled or Dry? A: Oiled filters (like aFe Pro 5R) generally offer the highest flow but require cleaning and re-oiling. Dry filters (like aFe Pro DRY S) offer slightly less flow but are much easier to maintain: just tap them out or vacuum them.
