Overview
The UPR Plug N Play™ Dual Valve Oil Catch Can with ECSS is the gold-standard PCV protection system for the Ford Explorer ST’s 3.0L EcoBoost. Two-stage separation — dirty-side catch can on one path, Electronic Clean Side Separator (ECSS) on the other — and it protects the intercooler the same way your factory PCV was supposed to but doesn’t.
EcoBoosts blow-by oil hard. Stock PCV routes that oil vapor right back into your intake charge, where it coats the intercooler core, drops charge-air-cooler efficiency, and coats intake valves (GDI engines can’t self-clean like port-injected engines). This kit traps the oil before it ever touches the hot side of your combustion path.

What The ECSS Actually Does
Most “catch cans” are just a dirty-side trap — they intercept PCV flow at idle and low load but do nothing when the turbo spools. UPR’s ECSS (Electronic Clean Side Separator) wires into the factory crankcase sensor and traps oil mist that gets forced out of the clean side specifically when the engine is under boost — exactly when modified EcoBoosts push the most oil vapor. No check engine lights. No EPS interference. No tuning around it.
- Multi-stage, multi-chamber separation — oil vapor drops, clean air continues
- Full-RPM-range protection — not just idle, not just cruise
- Factory electronics friendly — plug-and-play into OEM harness, no tune required

Installation
- Time: 20-30 minutes for a first-timer with basic tools.
- Difficulty: Plug-and-play — no drilling, no wiring modifications, no tune changes.
- Required tools: 10mm socket, flat-blade screwdriver for PCV quick-connect release, pliers for hose-end retention clips.
- Bracket mount: OEM hard points — the included adjustable bracket drops into factory-tapped bolt locations.
- PCV path: Disconnect the orange factory fitting (pull retention clip, push collar inward, pull apart — hold the ring firmly, it wants to stay seated). UPR quick-connect takes its place.
- ECSS wiring: Harness plugs directly into the factory clean-side crankcase sensor. Bolt the ECSS to the bracket and route the hose. Zero ECU changes required.
- First drain: Check after 500-1000 miles. Most drivers see 1-3 oz of captured oil on the first check. Drain interval stretches as blow-by stabilizes.

Performance Benefits
- Intercooler protected — no oil film coating the core means sustained charge-cooler efficiency as miles accumulate
- Intake valves stay cleaner — direct-injection engines don’t self-clean the back of the intake valve; catch can meaningfully delays the carbon buildup that kills DI power
- Throttle response — subtle but consistent — less oil vapor in the charge means cleaner combustion
- Fuel economy — marginal but measurable on long highway pulls
- Tune-friendly — no CEL, no EPS codes, no factory electronics interference — works with any SCT / Livernois / Aaron / Unleashed tune
