Description
The Mishimoto MMBCC-JLP-18PBE Baffled Oil Catch Can Kit is a direct-fit solution built specifically for the 2018+ Jeep Wrangler JL equipped with the 3.6L Pentastar engine, engineered to intercept the oil, fuel, and water vapor that this engine’s crankcase blow-by pushes into the intake. Machined from 6061-T6 billet aluminum in a twist-off can design, it pairs internal air turbulators and a baffle with a 50-micron bronze filter to scrub vapor before it re-enters the intake tract, addressing the blue-smoke-on-inclines issue that shows up on this engine when blow-by gets out of hand.
Every car engine depends on countless components of an automobile engine working together, and among the parts of a car engine most vulnerable to oil contamination are the intake components and sensors that keep automobile combustion clean and efficient. By trapping blow-by before it coats these car engine parts, this Mishimoto catch can helps your engine burn the fuel you actually put in the tank rather than a mix of gas and recirculated oil vapor, which helps maintain proper octane levels and reduces the potential for detonation. It’s a straightforward, purpose-built upgrade for anyone looking to protect essential engine parts on a 3.6L-equipped Jeep without adding complexity under the hood.
