xr8 220kw spark plugs?

josh_hartman · 08-01-2009, 11:07 AM

Well today i pulled out one of my spark plugs as i have a detonation problem and found out they are set to over 2mm. was just wondering does anyone know the part numbers for the correct plugs. got qouted $160 for iridium plugs but couldnt find any of the cheaper plugs. dont really wanna pay 20 a plug. so any parts numbers would be usefull. thanks

NGK BPR5EFS-13. It's what I use in mine. They should only be around four dollars each.

josh_hartman · 08-01-2009, 12:48 PM

just fitted those plugs and fixed my detonation problem

thanks for your help

**Peuty** · 08-01-2009, 01:02 PM

No worries. What did they cost if you don't mind my asking?

josh_hartman · 08-01-2009, 01:57 PM

umm around 5 dollars each. alot better than 20 each lol

falzoony · 08-01-2009, 03:40 PM

Yeah I just went to get plugs for my 6cyl and they were $22 dollars each so I think I will try and find some cheaper ones.

Lukeyson · 08-01-2009, 07:28 PM

glad to hear your prob fixed.

i got the irridium NGK's from Bursons for $14 each this week for my XR8, they are great plugs got 140'000 out of the last lot

I'm getting Denso Iridium Power spark plugs for my EF, plugs are so after looked these days. The denso Iridium's have the finest electrode point 0.4mm and are proven the best over all :-) Chu.....

LIES!! I went to Repco before changing mine recently, and they quoted me $22 EACH! That was for NGK Iridium, which according to them was the standard plug for the 220kW motor. Best I did was $17 through my mechanic! How the hell do you get em so cheap! :P

cause they arent Irridiums i would say

Because we don't use the Iridium plugs. Even NGK state they are the wrong plug for the XR8 as the gap is too large.

The BPR5EFS-13 is the standard replacement, I spoke to NGK to confirm this, and is the best plug for the job.

what sort of life expectancy you get out of them ones russ?-I replaced mine with iridiums last year but when they are due again WONT be going down that road again.

Iridiums are **supposed** to get you 100k but there is no way that I would ever leave them in there that long. I've also spoken to some leading tuners about this and they agree, spark plugs should be changed regularly and there is no way that you will get optimum power, efficiency and economy on plugs that old.

I use a colder heat range in mine (well I did with the old heads) and changed them every 3rd to 4th oil change, so every 15-20k. I do like to know that my engine is running as well as it possible can.

**Mont5.0** · 19-05-2009, 09:30 AM

and at 35 bucks for the set- much better option. Cheers for that.

Would my iridiums still have life in them?- i have done around 25-30k on them.

I reckon they'll still be ok for a bit, problem with plugs is they wear over time so you don't notice it when they are stuffed. Much like shock absorbers.

**Mont5.0** · 19-05-2009, 09:33 AM

a little off topic, but how often should leads and coil packs be changed- i did the whole lot together around 30k ago.??

Ford coil packs are only good for 80-100k. I've seen some terrible ones at 70k too though. MSD ones last a fair crack longer.

Leads I would think at about the 50-60k mark to play it safe. I do err on the side of caution though.

crakrz · 19-05-2009, 01:43 PM

I took Russels advice on the plugs, and Michael at ICE Ignitions gave me the same advice when I rang him for new leads. I was also advised to go one range colder than standard and run non-resistor plugs for best results (some will disagree), so far with no probs. So with the MSD coil packs, basic NGK plugs, and new high quality ICE leads, the engine has never run so sweet.

I love to see someone try get a set of plugs out of alloy heads after 100,000kms.

Iridiums, platinums or std plugs, im definately a beliver in regular plug changes.

For those not wanting to learn the hard way, even on cast heads, always put a light smear of anti-sieze on the thread when you put new plugs in. I have had to repair many heads, still on the engine, on site with the helicoil kit. 99% of the time it could have been avoided just by using anti-sieze on the thread.

I just replaced the plugs and leads on my NF fairlane v8 and were surprised to find motorcraft branded plugs and leads! could these be the originals? The car has done 165k. (PS I had no trouble getting them out... apart from breaking 2 of them cause of the angles i had to use the ratchet at

)
On the same topic tho, the car now doesnt run smoothly and seems to be lacking power like one cyl isnt firing. Tho it doesnt happen every cycle, just once or twice a minute at idle and i only occasionally notice it on the highway. I've checked that all the leads are on properly and that they are clean inside the lead ends. Is it possible for a lead to be faulty and if so how can u tell. The other option is that the plugs I got were wrong, I got the EL xr8 plugs (thinking they were optimised for performance) but the gap on those were smaller at 1.1mm as opposed to 1.4mm for the standard E-series v8s. Could this be the issue??

Have a look in the B-series section for the 5.4 3V. After doing my wifes Ghia the last plug had to shear didn't it. Lucky I prebought the removal tool from the States.

my coil pack is still the original factory one , from sept 2002 over 280k , seems ok , would be interested to see if a newie would make much difference ?

It will, they are a consumable and deteriorate over time so you generally don't notice them dying.

I've removed ones from a 110k car that were completely fried. Car seemed to run fine but after replacement the difference was quite noticeable.
