FTO AUSTRALIA

That is why i want to get some but no one seems to be able to tell me exactly if these denso ones are available for the mivec ones.

Also, I have tried calling uas but haven't had much luck either!

Also, does any one have any spare spark plug lead?
Just one will do.

If I have these I can get some one to make those upgrade for the leads.

if any one does, can they lend it to me or I'll even buy it off ya for a cheap price! Cause I'm not going to use it!

ive got a 97 gpx with mivec and looking for a place to change my spark plugs this week has been a nightmare. people telling me many different things. i was gonna get 6 denso irridium ones but apparently mitsubishi brought out as better one for $60 each. then apparently you should put different ones in the front. i dont think anyone wants to take my manifold off either. must sound like too much work .... the joys of having an fto!!!!

You don't have to put different ones in the front, but as standard the FTO does uses different ones in the front and back. The reason for this is the front ones are very easy to access, so they use normal ones there, but to get to the back ones is quite a job, so they use long life ones there so you don't have to change them as often.

If you put the long life ones in the front too, you won't have to change them as often.

Make sense?

yeah i would want long life ones all round

Can anyone tell me if the UAS back-to-back comparison was testing Iridium plugs versus *new* stock plugs? Or was it simply replacing stock plugs that were past their "best before" date?

I did a before and after Home Dyno run when I last got my plugs changed - standard platinum all round before and after. I got a higher torque curve across the board, by about 2 lb/ft, with fresh new plugs. So if this test wasn't against brand newies, it don't mean nuffink to me!

yeah i use them... they seem to work fine in all conditions... i don't know the part number that UAS supplied me...

so whats the difference between iridium and plantinum plugs?

Isn't it just what he tip is made from, ie Iridium or platinum. I think which ever are the more expensive (hte platinums?) are meant to last even longer and produce a better spark aren't they?

Hi guys,

I am still trying to find the right one for the fto to replace the spark plugs with...

As some of you guys have said that if you go to ngk web site in UK, they advice you to install different plugs on the front bank as opposed to the rear bank....which has completely different part numbers.
Why is that?

does any one know the part numbers of any of the upgraded spark plugs?
If so, do you mind sharing with me please?

If I know the part number then I should be able to cross reference and find the right one for me...

Please, if you know of any part numbers of any thing that is equivalent to the spark plugs for the ftos please supply the part number...

thank you all in advance...

you might want to re-read the 3rd message on this page

You might want to read my message before yours then!

I said it requires a different spark plug for front as opposed to the rear!

Did you get what I mean? A different spark plugs with completely different part numbers!
I work in the auto industry! I have already checked and they are different ones! It's go nothing to do with the fact that you use a normal one as opposed to the iridium ones for the front cause it's much easier to replace!
That's besides the point!

Btw, for those of you who are wondering, the UAS spark plugs aren't exactly what fits an FTO....it fits another car but it seems they found one that fits an FTO by trial and error!
I won't say what car it's for though!
Just to keep them happy!

I will try and find out why it's a different spark plugs used for the front to a rear ones.

Thanks

all the technical docs say its because the back ones are harder to change... the different spark plug in the rear has a longer life... which would imply its made from different materials...

myself i have the same alround and replace them all at the same time.

ummm... no, that is the point.

As Steve has said, and likewise you'll find the same info on many other FTO forums, the rear sparkplugs are long-life ones, while the front ones are standard-life ones, so that you don't have to replace the rear ones as often, as they are a bugger to get to. It has nothing to do with performance or anything like that, it just about ease of servicing.

If you want, you can put the long-life ones in both the front and back, it will cost more, but you won't have to replace the front ones as often as you would if you were using the standard-life plugs.

yeah irdium etc means nothing in terms of performance, they might state so but the difference would be nothing!

thats the problem with east/west V6 engines, a lot of them use platinum just for the sheer fact they are harder to change.

So is there an end to this SAGA? Any one found the right spark plugs? I'm after part numbers... for MIVEC ones...

I found this dyno graph.


This guy has a TT Soarer, i've asked him what where the plugs on the before dyno, so should get a reply soon... the after ones are Nippon Denso Irridum's...

does anyone happen to know the lifetime of the denso irridums cause i have done around 30,000 on this set, my mechanic said irridiums usually last 90,000. but the denso irridiums have a .4mm electrode (smallest i nthe world aparently) so their lifetime would be a lot less
