Overview

The Mishimoto Performance Air Intake is a precision-engineered upgrade designed specifically for Jeep Wrangler JL and Gladiator JT models equipped with the 3.6L Pentastar V6 engine from 2018 through 2026. This intake system replaces the factory air intake with a high-flow, direct-fit solution that enhances engine breathing, resulting in improved horsepower, torque, and throttle response. Built for Jeep enthusiasts who demand both on-road refinement and off-road durability, the Mishimoto intake delivers reliable performance gains without compromising the rugged dependability these vehicles are known for.

Whether tackling challenging trails or cruising city streets, this intake ensures your engine inhales cleaner, cooler air, optimizing combustion efficiency and providing a more engaging driving experience.

Engineered to maximize airflow and durability, the Mishimoto Performance Air Intake offers the following benefits:

• Up to 36% increased airflow compared to the stock intake for enhanced engine breathing
• Dyno-tested power gains of up to 10.8 horsepower and 11.4 lb-ft of torque
• Rotational-molded intake tube with integrated resonators for smooth airflow and reduced intake noise
• Custom high-flow air filter balancing superior filtration with optimal airflow

Filter Options

The Mishimoto Performance Intake offers two filter variants to meet different user needs and environmental conditions:

• Oiled Washable Filter: Provides maximum airflow and filtration efficiency, ideal for users comfortable with periodic maintenance and filter oiling.
• Dry Washable Filter: Delivers excellent filtration without the need for oiling, perfect for low-maintenance performance in dusty or wet conditions.

Construction & Design

The intake tube is crafted using advanced rotational molding technology, producing a smooth, seamless surface that minimizes airflow turbulence and maximizes volume. This process ensures consistent quality and exceptional durability, allowing the intake to endure the rigors of off-road use and extreme weather conditions.

Integrated resonators are carefully designed and dyno-tested to reduce intake drone while preserving the powerband where it matters most. The custom air filter is engineered to balance high airflow with superior filtration, protecting your engine from harmful contaminants. The entire system retains the factory mounting points and lower airbox, preserving the Jeep’s original fit and finish while enhancing performance.

Performance & Sound

By increasing airflow by up to 36%, the Mishimoto Performance Intake enables the 3.6L Pentastar engine to breathe more freely, resulting in dyno-proven gains of up to 10.8 horsepower and 11.4 lb-ft of torque. The integrated resonator not only smooths airflow but also tunes the intake sound, delivering a more aggressive yet refined engine note without excessive drone. This balance enhances the driving experience both on and off the road.

Installation & Fitment

Designed as a direct-fit upgrade, the Mishimoto Performance Intake installs easily using existing factory mounting points and hardware. No cutting, drilling, or permanent modifications are required, making it an accessible upgrade for both DIY enthusiasts and professional installers.
