Using Sea Foam Spray to clean GDI intake valves [SOLVED]

Is it better to use Sea Foam through the brake booster line or does it do better when slowly poured down the throttle body? Or should I use Sea Foam Spray?

Hey Cory. We get a lot of brake booster questions and our answer is always the same – don’t do it!

Instead, use Sea Foam Spray (an aerosol version of Sea Foam) applied through the throttle body. Sea Foam Spray will do a better job cleaning, feed all cylinders evenly, and safely remove carbon deposits without the risk of hydrolocking and harming your engine. It’ll do a great job cleaning GDI intake valves. Give it a try!
