NGK PFR6B for imprezas mate. I tried Iridiums in mine, and it ran like a total dog.
I use PFR7B's, as i am running more boost than std. But on a std car, the 6b's are fine.

Here you go:
Subaru have fitted both the 6b & the 6g to their engines but have never used a "d"
93-95my = PFR6G
96-2000my = PFR6B
2001-2007 = PFR6G
2008 on = SILFR6A
The difference between the "b" & the "g" is the material that the cntr electrode is made out of.
I have found the "g" to be a more stable plug and less prone to missfiring, there have been numerous occasions on classic cars where the fittment of a 7b induced a missfire which was subsequently cured by fitting 7G's.
