The Mighty Mouse Solutions WK2 Hemi Mild PCV Kit manages crankcase ventilation reliably in 2011-2021 Jeep Grand Cherokee models equipped with 5.7L Hemi engines, splicing into the stock PCV line to trap oil vapors before they reach the intake manifold for cleaner valves and improved throttle response in stock to moderately modified setups.
This U.S.A made draft can system uses -8AN or OEM quick connect fittings, supporting up to 800 HP while reducing carbon deposits and maintaining fuel efficiency in daily or off-road use. It addresses common Hemi blow-by issues better than factory components, ensuring consistent performance across varied driving conditions.
Each purchase includes the full kit: Billet aluminum catch can with sight glass, WK2-specific mounting kit, -8AN or OEM quick connect inlet and exit fittings, push lock hoses, and all hardware for straightforward bolt-on installation.
