the hot air maf worked wonders on a singular point injection subaru of the 80s. the giant intakes and increased stroke today with individual gadgets individualizing...hot air, cold air, who cares...it won't do much without changing to lean conditions by changing parts.
speaking of outback...
I heard an ej series engine run with higher compression and singular type plug fire, with a performance exhaust, non-turbo. It would be the only ej sube I would ever attempt, it was nice to see. The owner did admit the heads do not like to stay sealed. that is the shame of making it a "real" engine...I could only guess the consumption for power returned bringing a laugh while it lasted. Good ol days aint good ol stupid for some of us under the hood...
