Catch Can

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. 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. But Mishimoto has the solution.

Our 2018+ Jeep Wrangler JL 3.6L direct-fit 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, 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 during installation 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 a clogged valve slowing you down.

Like all Mishimoto products, this 2018+ Jeep Wrangler JL 3.6L baffled oil catch can kit is protected by our Mishimoto Lifetime Warranty. So, whether you’re climbing a treacherous rock face, exploring the wilderness, or just driving to work, you rest easy knowing your JL Wrangler’s engine is protected for as long as you own it.

Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what We’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.
