This is the most common question I face, and the resistance is futile!
In fact, all opposing thrust systems (which is every gasoline engine I have ever seen) will benefit from The Groove if properly applied. It matters not one iota who the manufacturer is.
Of course, intake manifold designs may have an effect, but those with poor designs will still experience gains, although maybe not in MPG's.
Remember the three rules and Do the MODS!
We all are anxious to hear of the first Alfa being done!
