Spark plugs...

[matbor]

Just wondering what brand and model number spark plugs S1 V8 disco owners use ?

Matt.

Best plug is NGK Iridium.

Cleaner burn in the 'messy' chamber that the Rover V8 has.

I'm on LPG, getting a good run from NGK BP6ES.

I have more trouble with leads.

Currently running stock Bosch leads coz I don't know any better :roll:

<span style="color:blue">NGK BP6ES is the standard plug for them....
equivalent to champion N9YC.......

whats the problem you have with the leads...?</span>

[Ralph1Malph]

About every 4-5 months, (4-8000km) a cylinder stops working. :evil:
So far has always been the lead. :twisted:

Different hole each time, no pattern I can tell. :roll:

Started sputtering and f*rting again last week, third time in the 18 months I've owned her.

In her defence tho, I have only changed the dodgy lead. So today I put 8 new ones and now she's sweet again https://www.aulro.com/afvb/

Is any particular brand lead better? I was tempted to buy a set of fancy twisted core jobbies but standard was way cheaper....

<span style="color:blue">if you dont listen to the radio.....go the copper core leads...... :twisted: :twisted: :twisted:



try and buy leads that are thick...they are better insulated.....
and when pulling the leads off the plugs...pull them from the boots....
not the actual lead as you stretch them and break the core internally.....
this break is not visible...the lead can look new and be cactus.....
as the spark now has to jump the break as well as the plug gap...it gets a bit weaker.....
and as it does so it arcs and burns the core of the lead internally until the
gap is too great for the spark to jump across.....


but i think by replacing the lot of them you have fixed the problem.....
they may have just been a really old set of leads.....
or just crappy to begin with......




and if you want to test your leads....just pull them off and check them with
your multimeters.....
you are looking for around 8,000 to 10,000 ohms per foot....
ie...if the lead is 2 foot long it should have around 16,000 20,000ohms....
any more than that they will usually give problems.......</span>

this is the best way to save money too, as you only replace leads that have failed,,
'though it will look like a gay mardi gra under the bonnet with all the different brand leads---

and i wouldnt use a champion plug as a sinker. NGK rules.

I use the http://www.magnecor.com/ leads, brought a good set a few years ago, had always had problems with the bosch and LRO ones, no problems since fitting the magnecor ones though. Might be luck though https://www.aulro.com/afvb/

Aren't those the ones they use in the Disco 2's ?? Expensive I heard and don't do much for the S1 Disco's ?? So I have heard, could of got my wires mixed up though https://www.aulro.com/afvb/ https://www.aulro.com/afvb/

I used them extensively in my vehicles...

Including the 3.9 supercharged V8 1995 Disco
The 5.0L stroker V8 Disco

My XR6
My V8 Calias
My ESP 351

They are definately worth the extra few $$$

And combine them with a set of 8.8mm spiral core leads and you'll never go wrong.

cant decide if you are a ford or holden man......?
or are you just a power man..... https://www.aulro.com/afvb/

Have heard good stuff about the spiral and iridium combo, not sure the financier would agree to the outlay tho!

Gunna try something different next time I have to lift the bonnet.

investing in a set of 8mm magnecore leads was one of the best things i ever did to my v8 disco.... made a lot of difference to it if my memory serves me right..

[muddy69]

I replaced the NGK standard with the more expensive iridium. Worthwhile investment in my case.
I feel my truck is running smoother and the burn feels cleaner.
Might look at those Magnecor leads. Any ideas on rough cost for 94 V8i.

[matbor]

Was a while ago, but think $60-80 !!!

How much are those iridium plugs ??

Matt.

[muddy69]

Fom memory, $18.30 ea from Repco. They had all 8 in stock whereas supercheap only had 5 and from memory supercheap was about $19-20.

my disco runs a resistive plug and allways has (BPRES) is this correct?
I invested in a set of topgun 8.8mm leads they seem ok in spark but all but two of the plug boots have become brittle and cracked within 2 years so i think i might try those magnacore jobies.
