Ive just bought a set of NGK laser platinum plugs from Graham Goode racing and notice the code on the box reads "PFR6B"
Does anyone know if these are appropriate for a 94 STi running between 1 and 1.1 bar boost?
Please help!
Alex

 

These are the standard scoob plugs

you would be better off with the "7" which is a cooler plug and would help curb detting

 

Thanks Russell,
Thats what I thought, (even though i was assured these were what graham goode racing use for uprated STis!)
Obviously an error, ill send em back.
