Part #: 41843

Overview

The Banks Power Ram-Air Cold Air Intake is a high-performance upgrade designed specifically for the Jeep Wrangler JL (2018–2026) and Gladiator JT (2020–2024) equipped with the 3.6L engine. As a leader in gas and diesel performance for over six decades, Banks Power delivers a cold air intake system that significantly enhances engine efficiency by increasing airflow, air density, and filtration quality. This intake system is engineered to provide reliable horsepower gains and improved throttle response while maintaining emissions compliance.

Ideal for Jeep enthusiasts seeking to maximize their vehicle’s power output and durability, the Banks Ram-Air system offers a substantial improvement over the stock intake, ensuring better performance in all driving conditions, including hot weather and off-road environments.

Key Features

The Banks Ram-Air Cold Air Intake combines advanced engineering and innovative design to deliver superior performance and filtration. Key features include:

• Best-in-class airflow of 782 CFM, an 82% increase over stock and 21.6% more than the nearest competitor
• 38% improvement in air density at the throttle inlet compared to the factory intake
• Fully enclosed, durable molded plastic housing that isolates intake air from hot engine bay temperatures
• Big-Ass Filter element with 672 square inches of surface area, 21% larger than competitors for extended service intervals
• Proprietary multi-layer woven cloth filter media that traps fine dirt and debris while maximizing airflow
• Engineered using computational fluid dynamics (CFD) and validated through flow bench, dynamometer, and on-road testing
• Designed to maintain performance even as the filter collects dirt, reducing restriction compared to standard filters

Construction & Design

The intake system features a rugged molded plastic housing that is fully enclosed to prevent heat soak from the engine bay, ensuring cooler, denser air reaches the engine. This design enhances combustion efficiency and power output. The Big-Ass Filter is crafted from a proprietary multi-layer woven cloth, offering superior filtration without sacrificing airflow. The large surface area of the filter allows for greater dirt capacity and longer intervals between cleanings, making it ideal for both daily driving and off-road use.

Every component is precision-engineered for a perfect fit and long-lasting durability, reflecting Banks Power’s commitment to quality and performance.

Performance & Sound

The Banks Ram-Air Cold Air Intake delivers noticeable horsepower gains by supplying cooler, denser air at higher pressure directly to the throttle body. This results in improved throttle response and increased power, especially under demanding conditions such as hot weather or heavy load. The system’s design also helps reduce the engine’s detonation risk by providing more thermal headroom, allowing for safer and more efficient combustion.

While primarily focused on performance and filtration, the intake also contributes to a more aggressive engine sound, enhancing the driving experience without excessive noise.

Installation & Fitment

Installation of the Banks Ram-Air Cold Air Intake is straightforward and designed to fit the 2018–2026 Jeep Wrangler JL and 2020–2024 Jeep Gladiator JT with the 3.6L engine. The system uses factory mounting points and requires no permanent modifications, making it a direct bolt-on upgrade. Detailed instructions are included to guide users through a hassle-free installation process that can typically be completed with basic hand tools.
