Hi, few questions...

1. What grade NGK Iridium spark plugs do I need for a 1997 ver.4 WRX RA (280ps model) ?

2. What diff oil do I need and how much do I need for the same car.

3. Also what gearbox oil do I need, again for same car.

thanks

 

NGK PFR6B if your car is mildly modded but I would go for the NGK PFR7B slightly colder & a good little upgrade

Diff oil - Castrol Syntran 75w 90, diff takes 0.8l & you can put the same oil in the gear box.

 

Correction PFR6B plugs are standard
