Mishimoto MMBC-JLP-18PBE Baffled Oil Catch Can Kit for 2018+ Jeep Wrangler JL 3.6L

There's nothing worse than getting your 2018+ Jeep Wrangler JL halfway up a rock face, looking back to see your friends' reactions, and seeing nothing but blue smoke. The 3.6L Pentastar is notorious for excessive amounts of blow-by entering the intake. This blow-by carries oil, fuel, and water vapor left over from combustion and too much of it causes smoking on inclines and while driving. This blow-by can also coat sensors and other intake components, reducing the performance of your engine and potentially causing knock. ---- Our direct-fit 2018+ Jeep Wrangler JL 3.6L Baffled Oil Catch Can Kit protects your engine by keeping blow-by out of the intake. This allows your engine to burn only the high-quality gas that you put in the tank. Our catch can employs a series of air turbulators, a baffle, and 50-micron bronze filter to clean the blow-by of vapors before it returns to your intake. ---- This catch can kit is a direct fit for your Wrangler, with no cutting or other modifications required. Installation of this catch can takes less than an hour thanks to the pre-cut hoses and installed stock quick-disconnects. A custom engineered 2.5mm steel bracket mounts our catch can to the fender rail, isolating it from engine vibration and movement for a lifetime of service. Also included with this catch can is a drain kit. Simply remove the plug from the bottom of the catch can and connect the drain kit to empty the catch can from behind the front wheel, without having to open the hood. This convenient feature lets you drain the can and get out on the road or trail in minutes. The included rubber cap prevents dirt and debris from entering the valve, so you never have to worry about clogged valve slowing you down. ---- Like all Mishimoto product, this 2018+ Jeep Wrangler JL 3.6L Baffled Oil Catch Can Kit is protected by our Mishimoto Lifetime Warranty. 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.

The Mishimoto MMBC-JLP-18PBE Baffled Oil Catch Can Kit is designed for the 2018 and newer Jeep Wrangler JL equipped with the 3.6L Pentastar engine. It helps capture oil, fuel, and moisture vapor from blow-by before those contaminants return to the intake system. By reducing buildup on intake components and sensors, this kit supports cleaner airflow, consistent engine operation, and improved long-term intake system maintenance. It is an effective upgrade for Wrangler owners who regularly drive on steep inclines, trails, or demanding off-road terrain.
The catch can uses a series of air turbulators, an internal baffle, and a 50-micron bronze filter to separate oil and other combustion byproducts from the crankcase vapors. The captured contaminants collect inside the can instead of coating the intake system. A durable 2.5mm steel mounting bracket secures the can to the fender rail while helping isolate it from engine vibration and movement. The bracket and catch can assembly are engineered for reliable service in demanding driving conditions.
This direct-fit Mishimoto kit is designed for installation without cutting, drilling, or other vehicle modifications. Pre-cut hoses and installed factory-style quick-disconnect fittings help simplify installation, which can be completed in under an hour with basic tools. The included drain kit allows the catch can to be emptied through the fender well without opening the hood, helping make routine maintenance faster and cleaner. A protective rubber cap helps keep dirt and debris out of the drain valve when it is not in use.
Backed by the Mishimoto Lifetime Warranty, the MMBC-JLP-18PBE provides a durable solution for reducing oil vapor buildup in the intake system of your 2018+ Jeep Wrangler JL 3.6L. This kit is intended for automotive applications and is not CARB approved.
