What spark plugs are the best to use ??
Hey guys
Last night I decided to change the spark plugs on my SV8 VZ , It has a 6 litre in it but funny enough when I pulled the plugs out they where iridium type plugs, I went to Bursons and they didn't have any of the same type so he gave me some NGK's. Am I stepping in the wrong direction and should I stick with the iridium or is the NGK's o.k.
Your thoughts would be greatly appreciated.
hey mate out of interest how many klms has your car done? are you changing then cause you just want to or because holden suggest changing them at 100,000 klm?
I bought the car about a month ago, the car has only done 50,000 Kms but I'm the type to go over the car and do the simple things like oil filters etc, just so I have peace of mind.
When I came across these plugs it stumped me why they aren't available as yet, but only from Holden ??? The guy at Bursons said through these in you will be fine, its bothered me all night and thinking have I done the right thing.

NGK's will be fine, as long as he gave u the Iridium's. Ive found out the Ones in my SV6 are Iridium's also.Originally Posted by black as
All i do is take out the plugs & give em a good clean.
U shouldn't need to change the plugs at 50k.

The NGK's he gave me aren't iridium type they are just a normal plug . The car seems to run o.k. but not quiet sure. I understand that the plugs don't need changing at 50k but I did it, its a bit like you don't need to change your oil till every 10k and most of us do it every 5k

No worries, mate.
Keep searching around for the Iridium's, as the car will be better suited to them.

as long as he gave plugs that are suited for that heat range, whether they need a resistor or not, ill assume he gave plus that suit the ls1's in the vt-vy's i think,
they will work, just replace then every 30-40,000km's if you got back for iridiums ask them for sparkplugs to suit a VE V8

The main reason iridium plugs are used is to ensure satisfactory long life service. (They'll be good for 100,000, whereas normal plugs need replacing much sooner.)
hello, i have a vz ss thunder crewman 6.0L gen4, i am woundering how do you change the spark plugs in it???
You cant go past irridium...performance and long lasting

lol @ people saying iridiums are good, they are a waste of money. What person in their right mind keeps plugs in a performance engine for 100,000ks?
Dont waste your money on them, just use NGK TR6's or even BPR6EF...change with every service.

Cant comment on how good iridium plugs actually are, but if the manufactureres are confident they will last for that length of time then Id go with that. If there is nothing actually wrong with them why change them, performance engine or not.
Many of us hang onto ideas from the past, hell, running cars on leaded petrol, spark plugs would barely last 5000mls before they were stuffed. Now, running lpg, I only replace them every 30000km, more out of fear that the plug after that they may just fatigue and fall apart rather than any obvious wear or drop in performance.

Performance engine ? what makes it a performance engine , the fact that it is 6 Litres ? that makes it a big engine, not a performance engine.

LOLZ, couldn't have been a better comment, exactly right, a performance engine would probably be getting rebuilt way before the plugs are due to be changed

There are many examples of manufacturers, corporations getting it wrong and not just by mistake.

If it was a cruising engine wit would have much different power curves throughout.
The fact they come with 270kw pretty much makes it performance. Maybe if they were like the 6's and had 190 or whatever they have you could say otherwise.

Dont wish to comment on that one,other than point out that the power output per litre for the 6L and 3.8L versions are about the same
On another tack, all other things being equal, an 8cyl should go further on a set of spark plugs based on there are eight of them to share the load around rather than six.

Having used "performance" plugs like NGK Iridiums, and Bosch Super4's etc in a stock engine in the past, I'm happy to say they do sweet FA for performance and are a complete waste of money given they cost 4-5x as much as a regular plug.
That said, I just picked up a set from Holden for the SS, and was surprised to find the OEM parts are in fact Iridums also.
Given that they cost $8.50 each (compared to something like $10-15 if you buy them from Supercheap etc) and that the service interval is 80,000km rather than 30-50,000km for standard plugs which would cost a little under half the price, I'm happy to use them knowing they were specifically intended for this application and are at a comparable price per km.

One also needs to factor in the labour charges that dealers impose for removing/fitting plugs for those that dont service their own cars, which is possibly the major reason that the irridium's get used rather than performance, reducing (theoretically)servicing costs)

Sure, but the labour charges would be the same regardless of the plug, and if you take it to the dealer you probably wouldn't have any choice but to use OEM, which in this case is the "performance" plug.

Sif.
DIY, it's pretty straight forward. Personally the NGK items for $1.30 a pop work just as well...

To an extent.
Champion spark plugs can go root themselves. So can those Bosch deals. I've never had any success with either brand.
*Champions fouled within 5000km.
*Bosch plugs actually melted. I checked that they were the correct plugs, and they were. I check three or four times thinking I must have made and error. I hadn't, they just plain sucked under heavy load.

The labour charges wont be the same......because they wont be changing them as often......
Given dealers probably charge $30-40? to fit and remove there will be some savings if they dont have to do it as often.
