Has anyone used these coils?
McCabe-Thiele (Ted):
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.

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.
