Spark plugs & oil

[33chinacars]

Well here we go again. What Spark plugs to use for 98/99 HSE 4.6. Standard according to Rave is Champion RN11Ycc ( NGK BPR5E equivalant). NGK partsfinder (UK) Says NGK BPR6E which is one range colder than Rave standard. Good price on ebay US for Iridium plugs But which one "5" or "6". What are your thoughts.I see that Paul fitted NGK BPR5EIX.
Also what engine oil do most people use. Any sugestions
Thanks in advance

NGK BPR5E (about $5 from repco) & Castrol Magnatec (which is free from brother who works from oil company) go into my 95 4.6 HSE (which is on lpg). Also, standard lucas leads via e-bay UK.

Probably should be running a different plug (for lpg) but haven't had a problem with these to date - burning clean and calm.

I'm using Valvoline SYNpower 5w 40 in my '00 Rangie HSE! I read somewhere (can't remember where) that you need to use fully synthetic oil in our engines, so that's what i've got!

As for spark plugs, i'm yet to replace mine so I can't comment!

Cheers

Thanks Guys for your replys

Also Keithy your 00 HSE will have different plugs anyway.

NGK BPR5EIX are good, I ran them for ages on petrol and LPG and they were fine. Also being Iridiums you get much longer life out of them, so less frequently dickin' around changing spark plugs.

I use Penrite HPR 15 oil, but I also subscribe to the theory that everyone has their own opinion on oil, and most oils with the right specs will do the job.

I use NGK BPR5ES. But plug leads.. anyone know any good quality right price ones?

[33chinacars]

Thanks all for your replies

Have order NGK BPR5EIX Iridium plugs from ebay USA $92.77 including shipping. Local price was $160. Yes I know there are cheaper alternatives but wanted to go with the Iridium plugs

Look up roverlord on e-bay aust if you want something now/asap.

Otherwise, try ebay.uk.co and just do a p38 leads search.

Both lots of prices should massacre anything from a dealer/stealer or LR specialist. :D

When you think about it, leads do a pretty good job surviving as long as they do with the heat inside the engine bay.
They do eventually start to break down and I am of the school of thought that if you replace with quality parts they 'should' give longer service life and work when you really need them to.
I found some great reading here:
Magnecor Race Wires (http://www.magnecor.com/magnecor1/main.htm)

Magnecores are a bit more expensive, I ended up going to a specialist place in Melbourne and after a very informative chat with the expert, instead of Magnecore leads, he made up a set custom made to suit my 2001 HSE 4.6.
He used Belden Ultra Low Suppression cable with quality boots which are a very similar construction to Magnecore. That with new plugs made a noticeable difference to my performance after replacing the old worn out leads that were in there when I got it. It now feels much more solid and responsive to drive.
From memory the leads worked out to around $12 or $13 each, which is pretty good considering they were custom made to suit my vehicle.
This place is in Melbourne, not sure where you are.
Hope this helps.

Magnecor leads on ebay $155 + postage.

MSD are also a good option too... They are the leads I run on my Chev!! You get to make them yourself too! Any length and size you like!

Hi All,
digging up an old thread I know, but rather than start a whole new one...

Just wanted to say that I put some new plugs in my '00 Thor P38 on the weekend, maybe it's just me, but it already feels a lot smoother...

Anyway, I used Bosch Platinum Plus FR7DPX. These were the same as the old ones anyway so I thought they will do the trick. They cost me $6.50 each from Repco (usually $8, also available from supercheap) Compared to about $25+ each for the champions, or $20 each for Denso, I figure this is a bargain! I asked the Repco bloke why they are so much cheaper, he reckons Bosch sell at least 10 times more plugs than the rest and can therefore be cheaper... Don't know about that...
Anyway, I reckon I got a bargain, time will tell me if I did or not:)

[Keithy P38]

I recently replaced my plugs from ngk's to britpart jobbies that came in a service kit from the uk, my engine idled smooth beforehand (30,000kms on standard ngk plugs), now it misses every now and then on idle... Ngk have my vote!

[PaulP38a]

onya Keithy - makes me feel better about the NGK PFR5G-11 "Laser Platinum Premium" plugs that have been in my '99 Thor for almost 3 years and still don't miss a beat. At $26 each, they'd better be good ;)

[Keithy P38]

I agree, ngk have always been in my engines, although I've just bought a D-max (settle down, its the mrs' new 4wd haha) so no sparkies in that! I should have left them in there, they were all still perfect... Shame I didn't keep any of them, if it ain't broke...

Ebay.uk absolute cheapest for iridium plugs about $90 delivered, got them in my '01 hse on gas.

I can't seem to find any evidence that iridium plugs are any better than platinum, except that they last longer with platinum lasting 60,000 MILES and iridium lasting 100,000MILES that's a huge difference... but so what? plugs are not that hard to change...

So why would one pay $25 dollars a piece compared to $8?

Have I made a "mistake" with the $6.50 Bosch platinums?

'cos I like to test stuff out, and I'm a mug :p

If the $6.50 Bosch plugs are rated for the P38 I am sure they will be fine. Let us know how they are doing after a couple of thousand Kms.

Cheers, Paul.

Well BOSCH is one of the leading ignition manufactures out there, so not suprised to hear that they sell 10 more than the rest. However i have the standard NGK plugs which are now due for replacement, and might try the iridium ones.

[RR P38]

Im not sure about leaving a plug in a cylinder head for 100,000km.
For most people that would be 5+ years.
Is there not more risk of getting a seized plug?
I quiet like pulling my plugs every 2 years and having a look see at how things are going internally.
A dab of Never seize might be wise with these long life plugs?

[Scouse]

A dab of Never seize might be wise with these long life plugs?I do that any way, regardless of how long the plug will stay in, especially in an alloy head.

[redandy3575]

Just ordered the NGK iridium off ebay, which seem to be a good deal.

I'd say Bosch, NGK are the pick when it comes to plugs. NGK i've seemed to have gotten a better run out of them in the past. Will be interesting to see how the iridium's go.

Just don't tell my old man, he used to work at BOSCH:angel::p

[bee utey]

I do that any way, regardless of how long the plug will stay in, especially in an alloy head.

And THAT above all illustrates above all why I prefer Bosch over NGK. Many sets of NGK plugs I have dragged out kicking and screaming out of alloy heads, the Bosch plugs just don't grab like that. Bosch plug threads are nickel plated which has a far higher heat tolerance than whatever NGK use. I don't lube Bosch plugs with anything other than a light spray of penetrating oil and I don't ever have plugs seize like the NGK's that other mechanics fit.

well I must be the unluckiest bugger in history as in my last 3 years ( albeit 9 cars ) I have had 2 stuck plugs !!! Both requiring a helicoil.. One in a Gu patrol with iridium plugs (Ngk) and the other in ........ you Guessed it a 4.6 range rover .... iridium again and this time bosch ....... perhaps just unlucky but some times it feels the more we spend ....... the more we spend !!! ....
P.s I didnt fit the iridiums to either vehicle I bought the cars with them in !!!!!!!!!!!!!
Also just for the .... of it my Hilux with a holden 308 runs a Bosch fusion (not listed for 308 but if you do research you can find many bosch fit non listed ) ...... smooooooooooooth .... well with lumpy cams !!! ha ha ha ha

Interesting.

Ummm......have you had a few drinks when writing this Phil??:p:angel:

Ngk plugs have a solid copper core, Bosch and Champion are only copper coated. Most Iridium/Platinum plugs will stick no matter what the threads are plated with, its the length of time they are in there, the type of alloy the heads are made of, and whether they have been hot a few times. Both Ngk and Bosch are nickel plated.
We get tight plugs all the time, no matter what brand, usually in an alloy head. A dab of anti seize on all new plugs cures seizing.
