Best spark plugs for a 2000 Legacy B4 RSK

[Andy_Mac]

i was thinking about changing the sparks myself as the mechanic i went to was going to charge a small fortune. just wondering what the best plugs are for this model, i've heard the iridium ngk ones are the best but don't know which one to go for.

is there anything else that needs to be done to the engine when replacing them or is it just a matter of getting the old ones out and putting the new ones in?

cheers

Go to the ngk site and you can look up the plug model for your car

[Andy_Mac]

tried that earlier but it must be linked to the auzzie site as it only shows the liberty gt and wasn't 100% sure it would be the same.

just found something on the uk site as all the rest only showed the 2.5l engine available, can anyone confirm that the part: BKR6E-11 is correct. i'd go for the iridium but need to be sure of the orig part first

Contact Forty One Automotive: http://www.fortyone.co.nz/ and they'll sort you out.

However, the BKR6E-11 would be correct, they would just need to regapped to .8mm

It's a 1-2 hour job absolute tops

Remove airbox

Remove Battery

Remove washer bottle

undo 4 coils

remove 4 spark plugs

repeat in reverse ;D

Iridium will not give you any more power but it will last a lot longer before needing replacement - it's like those eco-bulbs for the house, cost 4 times as much, last 4 times as long

Be prepared for a long wait for plugs from 41... I

Yeah true. The plugs I got were retailing here for almost $30 a pop at Supercheap/Repco. Got them through 41 for $17 a pop. The wait was worth it.

That was last year though so they might not be so expensive now.

Ok 41 has them for 11+ shipping. On the ngk website it shows them as being preset gap, does this mean its non changeable or just factory set?

i placed order for platinums in august, still waiting, but at 79.00 for all 4 delivered, i didn't think that was too bad!!!!

Not meant to regap platinum/iridium plugs. I reset mine though...

Very cheap price if iridium. Bkre6e11 is just a standard copper plug $5-7 rrp anywhere.

[Kiwi_Fozze]

i got the pfr6g's, pre gapped correctly, best to check them though.

[Andy_Mac]

So is regapping a pain or fairly easy? Do they not make a model thats set right for turbo legacys?

[Marky]

If I remember right the -11 at the end of the plug code refers to a 1.1mm gap in the plug

There's normally a .7 or .8mm ish alternative of some sort for turbo models off the shelf.

Or you can just regap them yourself with a feeler gauge, if you've got one. I've always been told it's not advised for iridiums as well (more risk of damaging the point of the electrode I think?) . It's literally just bending the tip of the plug (the bendy over bit) a bit closer to the point of the electrode.

Just buy copper ones, seriously the iridium is a waste of cash especially once you find how simple a plug change is
