Mishimoto Baffled Oil Catch Can Kit

2018–2021 Jeep Wrangler JL 2.0L Hurricane Engine

MMBCC-JLH-18CBE

Overview:

The Mishimoto Black Baffled Oil Catch Can Kit is engineered specifically for the 2.0L Hurricane direct-injected engine found in Jeep Wrangler JL models from 2018 to 2021. This advanced engine delivers impressive power and fuel efficiency but is prone to a common issue known as blow-by, where oil vapors and combustion gases escape past the piston rings and enter the intake system. Over time, this leads to carbon buildup on intake valves, causing misfires, reduced performance, and potential engine damage.

This catch can kit offers a proactive solution by intercepting blow-by gases before they reach the intake valves. Instead of allowing oil and fuel vapors to accumulate inside the engine, the Mishimoto catch can collects these contaminants in a dedicated reservoir, helping maintain engine cleanliness and optimal performance. Ideal for Jeep Wrangler owners who want to protect their investment and ensure long-term reliability, this kit is a direct-fit, hassle-free upgrade.

Key Features:

Designed with precision and durability in mind, the Mishimoto Oil Catch Can Kit includes several features that set it apart:

• Direct-fit design tailored for the 2018–2021 Jeep Wrangler JL 2.0L Hurricane engine for seamless installation
• 7.5 oz baffled catch can with internal air diverters to effectively condense oil, fuel, and water vapor
• Durable 3mm thick steel mounting bracket ensures secure placement and minimizes hose length
• Accommodates the factory pressure sensor to maintain check engine light (CEL)-free operation
• High-flow filter and direct-fit hoses engineered for optimal airflow and reliability
• Prevents carbon buildup on intake valves by diverting blow-by gases away from the intake tract

• Backed by Mishimoto’s Lifetime Warranty for long-term peace of mind

Construction & Design:

The catch can is crafted from high-quality materials to withstand the harsh conditions under the hood.

Inside the catch can, a baffled design with air diverters maximizes the separation of oil and fuel vapors from the air stream, ensuring only clean air returns to the intake system. The kit includes direct-fit hoses and a high-flow filter that maintain proper crankcase ventilation without triggering engine codes.

Installation & Fitment:

Installation is straightforward and can be completed in under one hour with basic hand tools. The kit is designed as a direct replacement for the factory PCV system components, requiring no modifications or special tuning. It fits a wide range of Jeep Wrangler JL models equipped with the 2.0L Hurricane engine, including Sport, Sport S, Rubicon, Sahara, Willys, and several special editions from 2018 through 2021. The included bracket and hoses ensure a clean, professional installation with minimal hose routing.
