Hey guys, NGK has my plug as ILFR6B but not sure it's right.. I keep On searching and it comes up as the H6 plugs..
Anyone recommend a plug? I'm looking at maybe going a notch colder than standard too..
Had some clowns on lib.asn recommend using non plat or irid plugs and go bog stock 3 dollar ones, have you seen the effort needed to keep changing plugs on the GT?? Subaru decided to put the chassis rail right in front of them... DOPES.
Which plug?

I'd go Iridium purely because its a PRICK to change them. Seriously, couldn't Subaru have made the chassis rail 2.5" further away?

Soft. 
Is it harder than a V6 Magna where the intake manifold has to come off?

Iridium = BAD.
don't touch.
go either stock standard (cheap ones) and change every 20k, or go platinum, and change every 100k.

I do this. (except I change them every 25-30k coz Im lazy
)I find NGK has a lower wear rate compared to other brands.

Ok, I am rather perplexed about this crap being slung on the Iridium plugs. I've never had a drama with them. Why does everyone give them grief?
MY00 Red RX, a nice daily that was sold off once the B4 became reliable...
MY02 Blue B4, aka 'The Project' - v8 JDM STi engine package and assorted other 'goodies' - Sold, then bought back for parts. Stripped and crushed.
MY03 Blue RX, the newer old daily, pretty well more B4 than RX now... In the process of being converted to the track toy... Watch this space!
MY02 Silver Wagon, H6 conversion, full blue/black leather and almost full black interior to go with it.
MY03 White/Silver H6 Outback, donor car for silver waghoon.
MY97 Silver RX, acquired to become track car, but plans changed. To be stripped and scrapped in time.

I bought them last time.
They don't seem to idle as well/smoothly in the B4 as the platinum ones did. Waste of money/time/effort.

Well I can't find platinum ones, and in the B4 I used BKR6EIX which i'm guessing will be the same for the GT,
they were Iridium plugs, and worked faultlessly.. no issue at all.
I think your B4 might idle rough due to the SA air it's intaking..

Well well well..
ILFR6B (iridium NGK) = $42.00 a plug rrp.
FR7KI332S (Double Platinum Bosch) = $14.50 a plug rrp.
Easy choice.

just for reference, stock NGK plugs are used from factory and recommended to be replaced at something like 48 months! this is what my book says.
and to be honest, i bought the super duper $90 plugs... and just over a year on i can tell they are in need of replacement, to start with they were awesome (as all new plugs are) but now i am having idle issues and such whereas the 3year old NGK ones are from my car went into someone elses as an emergency fix and they are still fine. another year on.
i think the plugs wear too fast with the tiny points they have. they are also affected more by any kind of fouling.
Its a pain yes but one of those ratchests with the flexy head (can be had for under $5 at supercrap/kmart) a inch long 3/8 extension bar and plug socket makes life 10x easier!

Nothing really wrong with Bosch I suppose. I just always found they wore faster than NGK.
I believe the key is regular replacement, so if you do that there is really no issue.
Reliability=Japanese
Engineering=German
Tip:
NGK make a neat little tool for spinning plugs in and out of hard to get places.
Its basically a rubber tube that you push over the ceramic of the plug. You still need a socket to crack loose and tension the plug, but it makes the process simpler.
Always put a small smear of high temp copper grease (such as 'Never Seize' or 'Wurth CU800') on the thread of the plug. They will go in and out much easier. *waits for the lube jokes*

I've got a spark plug socket that has square edges on the end to suit a 19mm spanner. Makes life easy.

Why Platinum > Iridium?
1) Platinum NGK = OEM STi plug. True story.
2) Build quality is better. Platinum is less resistant to wear and breakdown than Iridium. Iridiums wear out at about the same as the standard ones, so no point in going the iridiums. With the money you save, you could buy a case of beer or two, and buy standard plugs, and get the same result.
3) Lots of real world first hand evidence, here and overseas, to suggest that people have had dramas with iridiums, rather than platinums. Platinums are well known for being good to up to 100k kms.
If you're fouling NGK Platinums, you have something very wrong with your motor (hint: its not your plugs!).
Oh. NGK are the most consistent brand of spark plug in the world.
