Sparks ILZFR6D11

[Singapore stag]

Hi, I just bought plugs ILZFR6D11 Iridiums, Opie Oil tecnical department when contacted adviced that the gap is preset to 1.1mm.
I mentioned that my Bosch double platinum sparks were set at 1.00mm when I checked them. I was told to adjust them to the Z4 factory setting. If anyone have fitted the ILZFR6D11 to the N52 2.5i what gap did you set it at please.

Also yesterday when I cleaned the Bosch double platinums and the coil packs and then took it for a spin, I noticed the yellow engine light come on, it dissappered when I restarted the car. It has not come on since then, hence my ordering new plugs.
What could it have meant?
I have a theory, I mistakenly used copper grease on a couple of the plugs thread. Could this have been the reason? The symbol nornally represent emissions does it not?
Rgds,

Get the codes checked on the car as it'll give you an idea why the engine light came on.

I'd start there in case there's an issue somewhere.

You're better checking for codes a few times per year especially if there's been any work done on the car or a change in performance, fuel economy etc.

You should check the codes, take a note of them, clear the codes, run it a day or two then check to see what comes back.

Anything that comes back is most likely needing looked at.

Had them checked by garage diagnostics computer no code stored it was clear.
By the way , has the oil filler cap and gasket been superseded? I checked and it gave me this...
Numbers 5 and 6 instead of the original square gasket and cap.

Was the oil filler cap and gasket changed on the N52 when the engine covers changed colour from silver to black?

When i bought it it had and still has silver cover and black square filler cap and gasket. It has a slight leak so thinking of replacing them, but could not seem to get the right ones for sale. Went on Realoemnd it shows them to be superseded. Rather have them from stealers then take a chance on Ebay and buy questionable stuff as important as this.

Anyone to comment on the iridium gap setting before my plugs arrive?

Phone the local dealer and get the correct part number then buy it from eBay.

Thanks for your help Skelters, most appreciated.

You could of course get a price from the dealer and maybe buy it from there if they have it or can order it.

Had an on line chat with Chiswick BMW, they will ring or email me the part number and price tomorrow.

Got the oil cap from the stealers, it fits on tight and nice, unlike the previous which was loose when screwed on. £17.00.

Rgds,

Hi, An update on the NGK Iridium ILZFR6D11 spark plus.
I rang NGK and spoke to one of their technical advidors. They suggested that I leave the preset gap of 1.1mm as is.
Today I fitted the Iridiums and what a result!! The tick over was stable, constant and lower then before. Engine really running very smooth in all gears, no warning lights and performance was great.
Cleaned out the bores before I placed the plugs in. Had copper grease in it. Will never use the stuff on plugs again.
Several different manuals advice against it, also its conductive.

You’d want the grease to be conductive wouldn’t you? It’s how the plugs are grounded in order to spark, an electrically insulated spark plug wouldn’t perform very well :?

What it meant is if the grease gets on the electrode it wont perform very well.

That wouldn’t be a biggie, the grease would burn off fast with combustion temperature. A little grease isn’t a bad idea as seized plugs in the cylinder head can be a nightmare to sort out

Really!! Wont want that, is it having to pull the cylinder head out to rectify.
I know how bad a job that is. The Stag Ali heads are really hard to remove because the Metal bolts interact with the Aluminium heads and snap off, a nightmare scenario, someone on the Stag owners club invented a head puller but still a nightmare to get both heads off and they tend to warp. Stags suffer from head gasket failures.

I've always used a small amount of copper grease on plug threads for for years and countless changes without incident.
As Rob suggests, there's nothing worse than dealing with a stubborn sparker!

It's a good idea to check for tightness every once in a while, every 3 months at least or on any sign of a misfire.

Thanks for the info. Since I got new sparks , I will check them on routine inspections.

This is one of those questions that people will go one way or the other depending on what they believe, or have heard. Very first hit on Google about it was this

NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. .

This explains exactly why you shouldn't use copper/dielectric grease on spark plug threads:

I'm not saying don't do it, but based on the advice of the people who make spark plugs, I wouldn't...

Have you got ngk’s phone number? I’ll give them a call if an ungreased plug seizes in my cylinder head
