How important is it to get the EXACT engine code complaint spark plug for your engine?
Mechanic friend-of-a-friend sourced 4 plugs based just off my model and engine size.
Internet reveals that the plug model number is meant for the 3 engine codes that aren't mine, my one engine code is annoying and different, and the plugs are 4x the price online. I don't want to fit these, but it's confusing that a professional mechanic would have tried to fit them himself in my place...
I tried to find the exact specifications online to compare manually but its a shitshow.

as long as the length and the mounting type (thread + conical/flat flange) matches, you're ok

Gonna compare them.
I suspected as much, but trying to balance up being mugged off for some "premium" product, vs. putting the wrong thing in and being all "hurr why doesn't it werk".

what engine is it, what are the other engines?

Also check the distance between electrodes, though iirc it's the same on like 98% of engines.
They're almost identical.
The only difference is the place where the spark happens, you can't see it in the photo but its noticeably shorter (not just because the electrode is different)

>what engine is it
According to the interwebs this new plug is for the old 1.6 8v, and a few 1.6 16v.
My engine is a 1.6 16v with different engine code made towards the end of the model run.

Not really, you need plugs that run in your heat range and proper gaps.

The dimensions are identical except for this.

>what engine is it you fuck
VW Golf Mk IV, 77kW 1.6l 16v "BCB"

What car, what engine code.
You need to make sure it's in the proper heat range, and that the gap is the proper size. Wrong gaping can cause missfiring, poor fuel mileage and loss of power.
