The LIQUI MOLY Valve Clean has limited effectiveness on direct injection engines based on customer feedback and Q&A responses.
Why it's limited for direct injection:
In direct injection engines, fuel is sprayed directly into the combustion chamber, bypassing the intake valves
Since this product is added to fuel, it won't reach the intake valves where carbon buildup occurs in GDI engines
Multiple customers confirm it "won't work" or has "no effect" on GDI intake valves
Better alternatives for direct injection:
CRC GDI IVD Intake Valve & Turbo Cleaner
LIQUI MOLY - DIJectron Additive - Gasoline Direct Injection (GDI) Cleaner (22076)
Engine Intake Valve Cleaner Spray – GDI Safe | Cleans Intake Valves & Chambers, Lubricates Upper Engine, Storage Safe – 14 oz | Model SS14 | 2 Pack
Smilyeez BG GDI Air Intake & Valve Cleaner PN 260 With Pocket Screwdriver (1)
A intake cleaner (spray carb cleaner for example) will do more than anything you can add to your gas, esp most newer cars that are DI.

Its mostly snake oil at best and worse for DI motors.

If you have direct injection, this never even hits your valves.
Save your money here. Get a walnut blasting if you have direct injection.
As others stated, limited to no benefit for most modern engines which are GDI. A few manufacturers have dual injectors (GDI + Port injection), where it would work.
If you really have dirty intake valves, then you need a professional to open it up and walnut blast, or do some manual cleaning. If you have a small amount of buildup, or before buildup occurs as maintenence, then something sprayed into a vacuum line or intake may help keep it clean. There are lots of products available that claim to do this well. But you have to be careful with doing it, as it can cause some serious engine problems if you mess it up.
I am not a mechanic, but I do work on my car a decent bit and try to keep it running in tip top shape. Did learn some from a family of mechanics, though mostly older and they aren't as experienced with some of the newer stuff. YouTube has also been a great teacher. So don't take my advice, do your own research before you do something that could mess up your engine.
Put this in the original 2JZGTE out of my 1994 Civic EX. Really made the super charger come alive. Want to say I picked up at least 12lbs of boost with the additive. Laid down a solid 15.4 ET and got kicked off the track first time out. Nuff said.
I'm currently on a very tight budget and attempting to avoid the cost of walnut blasting. There are some DYI tuts online for that, but that is way above my ability.
