Hi all.
Me being a newbee n all, thought I should check...
I've a 1994 WRX wagon.
only mods I can tell are a dump valve and an induction kit.
What heat rating plugs do I need?
Thanks.

p.s. expect more of these type of posts till I learn more

 

Grade 6 NGK spark plugs.SJ.

 

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..

 

Pfr6b.SJ.

 

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

0.8mm for my particular model (UK T2000).

 

Nice one. Much appreciated

 

I wanna jump on this thread to. Iv got a v5 type r. What plugs do I need for it? If any1 has got a link that would be great

 

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

Ngk pfr7b

 

NGK pfr7g, if coil on plug.

 

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.

 

thats what i thought, so i checked anyway and made minor adjustment,was under a .mm, was just told/see this from another source,

 

Ah right lol! You did the right thing, always check them

 

whats the point in saying you cant gap them then send you plugs with the wrong gap , ?

 

Very true! It even says on the NGK boxes to check and set the gap lol
