2005-2010 Jeep Grand Cherokee WK Oil Catch Cans

The WK 3.7L and 4.7L cycle blowby vapor back through the intake via the PCV system, and over time the oil aerosol in that vapor leaves residue on the throttle body and intake walls that quietly degrades airflow and throttle response. Intercepting that vapor before it gets back in is the job of 2005-2010 Jeep Grand Cherokee WK Oil Catch Cans.

 

A catch can with a coalescing element inside is the design that actually works, since oil droplets collect on the separator material and drain to a reservoir for periodic emptying. Simple baffle-only designs pass most of the aerosol through and only catch the larger droplets, which is better than nothing but significantly less effective than a proper coalescing unit on a daily driver stacking miles.

 

Maintaining the intake's cleanliness on a platform where most owners care about longevity as much as performance is exactly what 2005-2010 Jeep Grand Cherokee WK Oil Catch Cans are for.
