N55 Delphi Ignition Coil Question

Null0Naru · 05-16-2020, 06:56 PM

So I recently replaced coils and plugs on my N55.

Bought the coils from ECP here in the UK for around £140 for 6. ECP is a little hit and miss when it comes to actually having correct parts, especially for more performance oriented engines like the N55.

The coils are Delphi GN10210-12B1. The correct part for the N55 appears to be GN10571-12B1.

The car is running with the coils I've put in, haven't noticed any problems. The only real issue is that the coils don't fit all the way down, so the little rubber lip doesn't sit over the top of the hole where the coil goes in.

Do you think this could be a problem?

I have found a set of the correct coils for £99 on eBay. Seller seems to have good feedback, but not sure if it's too good to be true in terms of price:

Don't use Delphi unless it has a BMW stamp on it.
Eldor is the current ignition coil supplier for BMW.
You can trust Eldor.

Any particular reason for that?

I'd assume it's from this thread? https://www.e90post.com/forums/showthread.php?t=1531626 Which is one guy, in the US, and the legitimacy of the coils was questionable.

Others have had no issues with running Delphi coils, either the BMW stamped ones or generic.

Also, Eldor, as far as I can see, is only available in the US, there are no suppliers in the UK or EU and there's no certainty that BMW will supply Eldor ones if you purchase from them, even with the £360+ price for them

Suprised Eldors aren't available in the UK.
Try searching with p/n: 12138657273 or ELD-R3516S00100.
Even aftermarket parts stores in South Korea have them in stock, in "BBT Technologies" box.

OEM Delphi might last long especially if you're not pushing above stock power level but the fact that they're made in China steered me away.

It's not just one person. I remember seeing a few more guys reporting issues on Facebook groups. They all ordered from FCP.
I'm no salesperson. Just trying to help.

Have found one place that sells them, though at £60 a pop, it's not particularly something I'm keen to spend money on to fix a potential non-issue. I do have all of my old coils, which should still be good AFAIK. Just replaced them as I was doing plugs anyway.

Mostly, searching for Eldor coils brings up options from the likes of FCP Euro and US eBay listings. Wonder if they didn't swap them out in all markets as even UK BMW's own eBay store is only selling the Delphi coils.

I try to keep clear of not trusting something just because of where it's made. Bosch coils were generally made in Germany but were found to be problematic, then Delphi was swapped in and generally considered to be much better.

I've read one post that says the little rubber boot can be slid down the coil to seal over the spark plug tube, so going to give that a go on cylinder 1 first rather than wasting my time taking off all the cowling only to find it can't be done.

EDIT: Did some quick import calculations. If necessary, I can order them from FCP Euro, which is around $200 for a full set, then duty and VAT is around 25% total, leaving me at around $250 or £200 total. Much better than the £360 it would cost me to buy directly in the UK. One of the few times importing from the US is worth it in terms of cost TBH.

EDIT2: No I can't. FCP Euro doesn't ship to the EU (ironic) due to GDPR... For some reason.

I've ended up buying a set of Eldors from the US. Price wasn't too bad

Are these N54 coils? Do they work better for N55? I have non-BMW Delphi coils and have some slight misfires so looking for other coil options, though didn't realise we can use N54 coils

Delphi is OEM for n55. n20 guys use them too

Schmidty335i · 06-12-2020, 08:22 PM

I just ordered a set of Eldors from FCP. i am getting some misfires at high rpms and jumpy idle sometimes. hopefully this fixes it. i have 59k miles and the stock coils with new NGK plugs at the moment. ill update on the results when i get the new ones installed.

Yes, I know they are the OEM coils but I didnt know we could use the N54 eldor coils on our N55s instead.

He does have Delphi (the non-genuine bmw oem delphi) and he said he's getting "slight misfires so looking for other coil options"

From what I see on FCP Euro's website, Genuine BMW Delphi were last reported to be made in Portugal and the OEM Delphi are made in China. Whether that makes a difference where it's made, I don't know, but browsing the forums it does appear some people have issues with the OEM Delphi, but most people seem to be running the OEM China made ones just fine.
