Thanks bud

I've found 2 types that I think might be the right ones... Internet can be confusing....
Do I need... BKR6E-11or BKR6EIX-11... PFR6B or BKR6EIX?
The later of each is said to be an upgrade from what I could make out.
Again, it's a '94 WRX but I didn't say before that it's an import.
Thanks again..

Make sure they are gapped properly too, wrong gap can cause a lot of trouble.

0.8mm for my particular model (UK T2000).

The upgrade to a pfr6b standard 2.0 impreza plug is a prf7b these will run fine on your 94wrx anything more is overkill imo

Are these the right gap aswell?

You'll need to gap them yourself mate, 0.8mm according to Subaru.

as above though i did ask this before on here and was told theyre gapped to 0.8 and doing it yourself can bugger them up, though i did check mine and they were 0.8.

How would setting the gap bugger them?

Just get feeler gauges and a spark gap setting tool. Less than a tenner for both. When I got new plugs they were between 0.9 and 1mm. Don't take it for granted they will be 0.8mm out of the box. The hassle that is caused by an incorrect gap is well worth the effort of checking and setting the gaps or having someone check them for you.
