Has anyone used these coils?

This set seems too cheap to be any good?!

True, but it “might” be a good? 😌

Indeed, it may be good.

Yes I've bought from Chinese sellers in the past.
My issue is any warranty is generally worthless also returning goods often has costly  hurdles to overcome.
If I can buy from a genuine UK based firm with a known returns policy with good feedback I buy from a UK firm even though it might be a few quid extra, not one of the sham fronts that you find on eBay that is some sort of warehouse with no UK phone number.

My general experience with Chinese parts and tools is not good.

The exception is well known brands with a good reputation.

But as they say you pays your money and takes your choice......

Thanks all, probably go for the previously mentioned ones, which don’t come with plugs, but are already being used by Ted

I emailed this seller to ask what the primary resistance of these is, knowing I won't buy, but I was interested, and this is their response:

"primary resistance is ?
we can resistance
thank you"

Just found this information that I posted here a while back. I think I spelt Hendler wrong.

"I fitted these (Hedler) as they are probably a temporary measure until I restore my originals.
They are Primary  5.11 Ohms - S 17.55 Ohms  made by Hedler the spec is on Hedlers website p/n 540612H
I did not use the screws shown in the picture mounted them in the original saddle at each end.
I switched the wiring so the poitive marked terminal was on the ignition feed side."https://www.hendler.co.uk/category/ignition-coils

Although this is the trade site you can still search the part number & find the coil specifications.

funnily enough I was looking at Hendler's website this morning and found them on ebay for £24.49, same part number

Yes that's the price each I think, mine were about £59.50  for the pair in 2022 so they will have gone down a tad.

Price updated.

Hello,
I bought a pair of coils from EBay for £37! They’re bound not to work!
I’ve just fitted them. They’re working fine so far after an ‘extensive’ 25 mile test.
The only problem is (as someone else here stated) the mounting holes are 90mm apart and the  standard fitting on my 550k3 is 100mm apart so you need to make up two little steel brackets. Measurements, 11mm wide, 28mm long with two 6.5mm holes with centres 10mm apart and 9mm from each end. Also as they have male spade connectors you have to make up 4 wires (2x female spade to male bullet black with white stripe and 2x female spade to female bullet one blue and one yellow). They need to be about 250mm long. I don’t think the coil connections are polarised so I just wired them the same way as each other.  I suppose we’ll see how long they last.
I was also quite pleased I did this as the yellow wire connection just fell apart and was due to fail. Good luck with it.

Why not indicate which you bought? We're in the dark.

[beardylondon]

BTW I went for these Hedler ones, as recommended by Ted and also Ash said the higher resistance of these is better than cheaper versions.

They are yet to arrive, but I will report back.

Is the primary resistance quoted?

A link to the actual item would help.
