Mishimoto MMBCC-JLH-18CBE Baffled Oil Catch Can Kit for 2018-2023 Jeep Wrangler JL 2.0L

The direct-injected and turbocharged 2.0L Hurricane engine found in the 2018-2023 Jeep Wrangler JL is the most advanced engine ever fitted to a Wrangler. But, despite all the high-tech features that make the Hurricane great, It's still vulnerable to a very low-tech problem: blow-by. The fuel efficiency and increased power of direct injection comes with the threat of carbon buildup. As fuel and air get squeezed in the cylinder, some of the mixture leaks past the piston rings and carries oil from the cylinder walls with it. This mixture is known as blow-by. To prevent crankcase pressure from building up, the blow-by is then vented into the intake to be reburned. Blow-by becomes an issue with direct-injected engines when it passes the intake valves. Without fuel spraying over the valve, There's nothing to wash off the blow-by and heat from combustion eventually causes it to build up as carbon on the back of the intake valves. That carbon buildup prevents valves from closing fully and disrupts airflow. The result is poor running, misfires and, if left long enough, engine damage. The best solution to the problem of blow-by buildup is prevention. Instead of letting blow-by enter the intake, the Mishimoto 2018-2023 Jeep Wrangler JL 2.0L direct-fit baffled oil catch can kit diverts it away from the intake valves and into a 7.5 oz catch can. You can then recycle the contents of the catch can with your next oil change. The internal air diverters and baffle of our catch can thoroughly condense oil, fuel, and water vapor so that the only air flowing through your intake is fresh air. In addition, our direct-fit lines and high-flow filter ensure CEL-free running. Like all Mishimoto products, this 2018-2023 Jeep Wrangler JL 2.0L catch can kit is protected by our Mishimoto Lifetime Warranty, so your JL can also be protected from blow-by for a lifetime. Engine oil catch can kit designed to capture oil vapors and prevent buildup in the intake system. Helps maintain efficiency, reduce carbon deposits, and improve performance with durable components and easy installation.

• Durable 3mm thick steel bracket mounts the catch can securely while maintaining short hose runs
• Accommodates factory pressure sensor for CEL-free running
• Installs in under 1 hour

The Mishimoto MM​BCC-JLH-18CBE baffled oil catch can kit is designed for the 2018-2023 Jeep Wrangler JL equipped with the 2.0L Hurricane direct-injected and turbocharged engine. Direct-injection systems can allow oil vapor, fuel vapor, and moisture from blow-by to enter the intake system, where combustion heat may cause carbon deposits to form on the backs of the intake valves. Over time, this buildup can restrict airflow, contribute to rough running and misfires, and reduce engine performance.
This direct-fit Mishimoto catch can kit diverts blow-by away from the intake system and collects contaminants in a 7.5-ounce catch can. Internal air diverters and a baffled design help condense oil, fuel, and water vapor before they reach the intake valves, while the high-flow filter allows clean air to continue circulating. The result is a cleaner intake path and added protection against the effects of blow-by buildup. The contents can be drained and recycled during routine oil service.
Designed specifically for the Jeep Wrangler JL 2.0L, the kit includes direct-fit lines and a durable 3mm steel mounting bracket that keeps hose routing short and secures the catch can in place. The bracket also accommodates the factory pressure sensor to support check-engine-light-free operation. Installation can be completed in under one hour using common tools, making this a practical upgrade for daily driving, trail use, and long-term engine maintenance. Like other Mishimoto products, the MM​BCC-JLH-18CBE is backed by the Mishimoto Lifetime Warranty.
