True. So maybe some type of intake cleaner fed thru a hose into the plenum or sprayed into the air intake?My understanding is by definition, fuel doesn't come in contact with the intake valves and so a fuel cleaner would have no effect. With BMW there is a walnut blast procedure to remove the carbon. I think Toyota (or one of the mfg) combines both direct and port fuel injection so that fuel can still clean the intake valves.

Any ideas? Direct feed system into plenum?You're not going to do much good cleaning the rock hard intake valve deposits spraying anything into the intake tract once the deposits have formed. There are dummies on YouTube that make mosquito fogging videos with such method and act like it's the deposits burning when it's actually the spray.

True. But are they basically a requirement with these engine designs? Do they work well?Plenty of products out there just a Google search away. https://knowhow.napaonline.com/how-to-use-crc-gdi-intake-valve-cleaner/
Try that out on your little SUV. A 5 second sedan like the Civic R doesn't need that.Just a quick thought as I run on by ...
How 'bout a NOS fogger system? Enjoy an extra 50-75 HP RED button boost, and later when you blow the plastic intake off racing a R- spec honda, it will be easy to get to the intake ports
What deposits are you referring to?We know that direct injection designs can allow carbon build up unlike other designs. Does this mean that they should probably have maintenance doses of fuel system cleaners or is there a different way to keep deposits low?
Only way to make contact would be inject early, and use something like Miller cycle. Closing intake late, so you push fuel spray a bit to intakeMy understanding is by definition, fuel doesn't come in contact with the intake valves and so a fuel cleaner would have no effect.
Yep - some OEM outboard products are a strong dose of Techron with a new decal …Hyundai specifies techron with every oil change in my owners manual, so I use that.
