Has anyone used these coils?

[Brocky2]

I measured the primary resistance at 4.7 ohms.
I can’t work out how to share the actual link but copy and paste this into eBay and you’ll get it.

Is the primary resistance quoted?
A link to the actual item would help.

This ^ and is it a known brand? Advice in general: If no brand and made in China, abstain from ordering.

Looks like these then. branded as SMP made for the seller in Taiwan?

Received these, both appear genuine and boxes too, both with unpainted NGK logo

They are the same I have. Tip: use a little vaseline, silicone oil or similar inside the upper sealing rubber before you screw the HT wire on. That rubber seal is a bit tight and could therefore resist slightly and give you the feeling you are already there, when in fact you're not. Then you would have a bad connection.

Hi All

So I am starting to get my head round fitting the new coils....

As per photos below, the original wiring is coloured blue and black/white and yellow black/white the other side.

The new ones, as per bottom photo, the wires are solid red and white, so my question is, which way round do the wires go?

thanks in advance!
