Well, that engine was used for quite a few different applications.. So I need the year and model of Subaru that it is in, to be able to give any kind of accurate answer.
Customer: replied 4 years ago.
i thought I replyed but there was a page error, I have a 1990 right hand drive subaru legacy GT. ej20G
Expert:  ase_master327 replied 4 years ago.
Yes, I have been getting some errors on the site today as well.. They have been reported.. Was yours something like server failure or similar?

Anyways.. ok.you have the 'old style' EJ20G engine..
Here is the recommended plugs and gaps on this engine:

NGK ---------------- PFR7B
The gap on these spark plugs should not be adjusted as that is done when they are manufactured. They are gapped to 0.8MM..

SPARK PLUG TORQUE
13 - 17 ft lb (18 - 24Nm)
