Mishimoto Baffled Oil Catch Can (F&R)

2018–2025 Jeep Wrangler JL / Gladiator JT 3.6L Pentastar V6

Part #: MMBCC-JLP-18PBE

Overview

The Mishimoto Baffled Oil Catch Can is a precision-engineered upgrade designed specifically for Jeep Wrangler JL and Gladiator JT models from 2018 through 2025 equipped with the 3.6L Pentastar V6 engine. These engines are known to experience excessive blow-by gases that introduce oil, fuel, and water vapor into the intake system, which can cause blue smoke emissions, reduced engine efficiency, and potential knock issues.

This direct-fit catch can effectively captures and filters these harmful vapors before they reach the intake manifold, ensuring cleaner air intake and improved engine performance. Ideal for both off-road enthusiasts and daily drivers, it helps maintain engine health under demanding conditions such as trail driving, rock crawling, or heavy load scenarios.

By preventing oil and combustion byproducts from contaminating intake components and sensors, the Mishimoto catch can preserves throttle response, reduces smoke emissions, and extends overall engine longevity.

• Internal baffling system combined with air turbulators to effectively separate oil and vapors from blow-by gases
• 50-micron bronze mesh filter that cleans vapors before recirculation into the intake
• Durable 2.5mm thick steel mounting bracket isolates the catch can from engine vibrations for long-lasting stability
• Pre-cut hoses and factory-style quick-disconnect fittings for a hassle-free installation in under one hour
• Convenient drain kit allows mess-free emptying through the fender well without opening the hood

Construction & Design

The Mishimoto catch can is built from high-quality materials engineered to withstand the rigors of off-road use and daily driving. The core canister features a robust internal baffle system paired with strategically placed air turbulators that promote efficient separation of oil and vapor from blow-by gases. This design minimizes contamination and buildup within the intake system.

A 50-micron bronze mesh filter further refines the vapor before it is recirculated, reducing the risk of oil deposits on intake valves and sensors. The included 2.5mm thick steel mounting bracket is custom-engineered to securely attach to the vehicle’s fender rail, isolating the catch can from engine vibrations and movement to ensure consistent performance and durability.

Installation & Fitment

Installation is straightforward and requires no cutting or modifications to your Jeep.
