I just bought a 2011 Ford F150 with 91,000 miles. Engine is a 3.5 V6 EcoBoost with twin turbos. It is also GDI so I am worried the intake valves might get heavy with carbon deposits. For cleaning intake valves should I treat through brake booster or use Sea Foam Spray through the throttle body?

We strongly encourage you to use Sea Foam Spray through your Ford’s throttle body. It is much safer, much more effective, and will feed all six cylinders evenly.
