Worth the $$$ - NGK Iridium Spark Plugs?

[naiwiboo]

Hey,

i'm just wondering if anyone has used the NGK Iridium Spark Plugs in their '33?

If you believe the brochure they're a lot better, but I've heard people say they're not worth the money - just wanting to know if anyone has had any experience with them or anythin similar - good or bad?

Thanks Guys!

i have the iridium heat rating 7 in mine. cannt tell the different actually, but they will last longer in a well tuned A/F environment.

i dont' know what plugs i've got in my car .. i've never changed them ... another option would be to get cheaper ones but change them more regularly ..

I too spent the $$$ on Iridiums and were not that impressed with them... next time I'm just going to go the platinums.

I've got NGK Platinums and I'm happier with them than the crappy copper ones that were in my car when I got it!! I've heard that Iridium doesn't make all that much of a difference...

Well my dad's GTR had problems with the platinum plugs fouling at anything over 1.2bar. we fitted the iridiums and they made a massive difference. much smoother and no probs at high boost. im going to get them for my GTS. i dont know if it would make a huge diff on a low powered car like mine. but it made a big difference with his.

Thanx for the speedy replies guys! does anyone know what the NGK platinums go for at say Autobarn/Repco? - don't wanna get ripped off!

also does anyone know the part number for these plugs for an R33 (NA)?

considering ive got an NA, what gap width would you reckon i should run them at?

Thanx for your help again

[bbenny]

hey price is about $19.50ea

I dont know what u should gap them too. i know for turbo RB engines its 0.8mm but on the packet the iridiums say not to change the gap because the tips are very fine and fragile.

I gapped them to 0.8 anyway and they have been pretty good.

I think normal NGKs are fine (the copper ones)

[Miss*33]

I paid $18.50 each for mine at Autobarn.

19.50 and 18.50 each for a spark plug. oh my god what a waste of money!

nothing else needed.

[Miss*33]

Yes it is a waste of money, but if you want your car to run nicely and not #*&% up, then why be tight...if you spend that much on a car, you look after it!

[akeenan]

if you spend that much on a car, you look after it!

i know how to look after my car. some things are an over kill this being one of them.

[Miss*33]

Yeah I know, a lot of things are overkill...but they spin a whole lot of crap about how much better the expensive stuff is, I guess people just believe them, a lot of us being those people!!!

I was quite happy to go with the cheap copper plugs until he explained to me why the Platinums were better...made sense to me so I bought them!

[ron]

like i said earlier i have iridiums in mine at the moment. and im happy with them.

i paid $21 each i think, sure they spark stronger due to the finer tips. but i dont expect to see any big performance gain.

but the good thing is i wont have to change them for another 100K k's or so. (NGK quote 150K actually)

you think $20 is expansive for a spark plug how about going through 3 set in 5 months i dont know why my car keep fouling but it abit better now .

[CMS Drifter]

I can get iridiums for about $16 ea.......

There wont be much gain from platinum to iridium.

The main fact is that they are a longer lasting plug. Standard copper plugs "wear out"

I haven't noticed any significant difference in performance in my gtst.

[naiwiboo]

CMS Drifter - where can u get iridiums for $16?? that seems heaps cheaper than the usual price

[CMS Drifter]

i get them trade price from coventry's here in wa

[Junior Zilla]

you should be able to get them cheaper through ya mechanic.

my mate does it that way
