aFe Carbon Fiber Cold Air Intake

2012–2024 Chrysler 300, Dodge Challenger, Dodge Charger 6.4L 392

Part #: 51-12172-C

Overview

The aFe Carbon Fiber Cold Air Intake System with Pro DRY S Filter is a premium airflow upgrade designed specifically for the 6.4L 392 HEMI engines found in Chrysler 300, Dodge Challenger, and Dodge Charger models from 2012 through 2024. This intake system delivers a significant performance boost by increasing airflow efficiency while enhancing engine bay aesthetics with its sleek carbon fiber construction. Ideal for enthusiasts seeking reliable horsepower and torque gains without compromising factory fitment or requiring modifications, this intake is a direct bolt-on solution that elevates both power and style.

Engineered to feed the monstrous SRT 392 engine with cooler, denser air, the system improves throttle response and overall engine efficiency. Its combination of a large 7-inch conical air filter and a dyno-proven carbon fiber intake tube ensures maximum airflow and durability for spirited driving and track use.

Key Features

This intake system incorporates advanced design elements and high-quality materials to optimize performance and ease of installation:

• Dyno-proven gains of up to +21 horsepower and +27 lb-ft of torque
• Measured airflow of 600 CFM at 7" H2O, outperforming factory intake by 9%
• 100% twill weave carbon fiber intake tube with a high-gloss clear coat finish
• Massive 7" inverted top conical 360-degree radial flow Pro DRY S air filter with three layers of synthetic media
• Powder-coated, one-piece aluminum heat shield to block engine heat and protect intake air temperature
• Utilizes factory mounting locations for a secure, no-drill installation
• Washable and reusable Pro DRY S filter for long-term convenience and cost savings
• Includes all necessary clamps, reinforced couplings, and hardware for hassle-free installation
• Direct bolt-on fitment with no cutting or modifications required on OEM parts

Construction & Design

The intake tube is crafted from 100% lightweight carbon fiber with a twill weave pattern, providing exceptional strength and heat resistance while reducing overall weight. The high-gloss clear coat finish not only protects the carbon fiber but also adds a premium visual appeal under the hood. Complementing the intake tube is a durable, powder-coated aluminum heat shield designed as a single piece to effectively isolate the intake from engine heat, ensuring cooler air delivery for improved combustion efficiency.

The Pro DRY S air filter features a large 7-inch diameter inverted top conical design with 360-degree radial flow, maximizing surface area and airflow. Its synthetic media is oil-free, washable, and reusable, making maintenance straightforward and environmentally friendly.

Performance & Sound

With dyno-tested results showing up to 21 horsepower and 27 lb-ft of torque gains, this intake system significantly enhances engine breathing and throttle response. The increased airflow capacity helps the 6.4L 392 HEMI engine perform more efficiently under load, particularly during aggressive acceleration and spirited driving. Additionally, the intake produces a more aggressive induction sound, giving your vehicle a sportier and more commanding presence without excessive drone.

Installation & Fitment

The aFe Carbon Fiber Cold Air Intake is designed for a straightforward, direct bolt-on installation that requires no cutting, drilling, or permanent modifications to OEM components. It mounts using existing factory locations, allowing for a secure fit and quick installation process. All necessary hardware, including clamps and reinforced couplings, is included to ensure a hassle-free setup.

Please note that this intake system is not compatible with vehicles equipped with the shaker hood or when using the aFe POWER throttle body spacer (P/N: 46-32007).
