Hi, everyone. I'm a first-time poster from Houston. I've not owned a Subaru before, but I'm very interested in the Ascent. But, does anyone know the technology used by Subaru to prevent carbon build-up on the intake valves? For example, Toyota adds port fuel injection to spray, intermittently, fuel on the outside of the valves. Mazda uses valve timing to ensure that the metal in the valves gets hot enough to burn off the carbon. Thanks for reading!
