Spark plug gap

Interesting idea, but, from what I've heard, Temu is very much "you get what you pay for"...

Well I've been using it for at least 18 months now and got some downright bargains.

And some products are downright dangerous...!

But feel free to buy them on Ebay if you want....as they're currently £48 on there!
If you're not content with anything, simply send it back up to 3 months later, free of charge, for a full refund.

On eBay there is much more of a guarantee that the products are made to appropriate levels of safety and the refunds process is monitored and controlled (although, speaking as a seller on there, sometimes it's skewed *too far* in the direction of the consumer!)

With Temu, I have little doubt that much of their profit comes from people deciding it's not worth the while to send stuff back and just binning it.

Anyway, this is Off Topic for this thread, so I'll leave it here.

Well, my post was totally on topic and relevant actually. I'm sure a quick double check with a Vernier measuring tool would answer your question about the 'safety' of this metal coin and i will even go out on a limb and guess it's not gonna randomly catch fire on you as it can't be PAT tested. 
And just for the record, if it did turn out to be useless they'd refund you in approximately less than 1 minute, AND you get to keep it, bin it, or do whatever you fancy with it at that price. This is all knowledge from being a regular customer, so all a bit of a moot point you brought up there.
