Fix inconsistent boost, sluggish turbo response, and underboost issues on your 3.5L EcoBoost with this aftermarket Turbocharger Boost Pressure Solenoid Filter Kit, designed as a cost-effective alternative to OEM part numbers BL3Z-6L625-G (driver side) and BL3Z-6L625-F (passenger side).
This complete kit replaces both turbo boost solenoid filters at roughly half the cost of OEM, while delivering the performance and fitment needed to restore proper turbocharger boost control.
Critical Service Recommendation (Some Shops Overlook This)
These turbo boost solenoid filters should always be replaced anytime they are removed, and especially during:
- Turbocharger replacement
- Turbocharger rebuilds
- Turbo system service or upgrades
Reinstalling old filters can reintroduce contamination into the boost control system, leading to:
- Premature turbo issues
- Inconsistent boost pressure
- Reduced lifespan of new or rebuilt turbos
Replacing these filters during turbo service is cheap insurance for long-term reliability.
Why This Kit Matters
The factory turbo boost solenoid filters on EcoBoost engines are known to clog over time due to:
- Oil vapor contamination
- Carbon buildup
- Dirt and debris intrusion
Once restricted, these filters can cause:
- Erratic or low boost pressure
- Slow turbo spool
- Hesitation under acceleration
- Boost-related trouble codes
Replacing both filters is a critical but often overlooked fix that can dramatically improve turbo performance.
