It’s paired with an 8-layer oiled filter that’s not only reusable but also engineered to trap dust and debris without choking off airflow. The enclosed airbox and optional airbox plug give you the flexibility to run wide open for max flow or dial it back for added protection in dirt-heavy environments.

This upgrade is a smart move for any L5P owner looking for an instant improvement in throttle response, engine tone, and overall drivability.

Designed To Optimize Flow And Seal Every Connection

The S&B 75-5144 Cold Air Intake isn’t just about more airflow, it’s about delivering that air with precision, consistency, and reliability. Its one-piece air tube is shaped for minimal restriction, forming a smooth pathway from the airbox to the throttle body to reduce turbulence and pressure drop. At the heart of the system is an oversized 8-layer oiled cotton filter, designed to be washed and reused, offering long-term value and excellent filtration. The airbox features dual inlet ports to maximize intake volume, and an optional plug is included to fine-tune airflow depending on your environment. S&B also incorporates a silicone scoop that draws air from the factory hood duct, increasing cold air delivery without additional modifications. Every coupler, tube seal, and plug is made of premium silicone rubber rated up to 400 degrees Fahrenheit, ensuring lasting durability even under high engine bay temperatures. The MAF sensor plate is injection molded with an OE-style O-ring seal to ensure leak-free operation and accurate readings. Installation is a direct bolt-on with all hardware included, and it’s fully compatible with stock tuning—making this a high-performance intake that keeps things simple.
