Overview:

The Mishimoto Baffled Oil Catch Can is a precision-engineered solution designed specifically for Jeep Gladiator (2020–2022), Jeep Wrangler JK (2018), and Jeep Wrangler (2018–2021) models equipped with the 3.6L Pentastar engine. Known for excessive blow-by gases entering the intake system, these engines can suffer from oil, fuel, and water vapor contamination that leads to blue smoke emissions, reduced engine performance, and potential knock issues. This direct-fit catch can effectively captures and filters these harmful vapors before they reach the intake, ensuring your engine breathes cleaner air and runs more efficiently.

Ideal for off-road enthusiasts and daily drivers alike, the Mishimoto catch can helps maintain engine health during demanding conditions such as rock crawling, trail driving, or everyday commuting. By preventing oil and combustion byproducts from coating intake components and sensors, it preserves throttle response and overall engine longevity.
