Repair issues and fixes

I am going with the 3/4 inch by 1/8 inch neodymium dual magnet external mount (@navguy12 design). I am ordering two regular steel Hyundai plugs- are they( the fill and drain) the same part# 00810-17121? and do you think 2 would do the job ?
I ordered a pack of 5 and they arrived yesterday. My plan is to order 2 original plugs and 2 liters of 00232-19063 oil, pick them up, attach the 2 magnets to each plug with Scotch 414DC-SFEF mounting tape, then take the car in to have it changed in about a month while having the 2 year check and brake lubrication service done. I figure if I have the new plugs ready and hand them to the service dept, it will make it easier, than trying to fit them on the oily old ones. I will request (this time) to have the leftover gearbox oil (.9 liters) and the old plugs, (including the old oil in a container I will provide) returned to me...this will be the second change...first @ 8,699 kms, car now at 13,380 kms, should be ~ 14,000 kms when that 2nd check is due.
Thanks for your time and advice @KiwiME and @navguy12
Edit, I opened the parcel and discovered they sent me 5 containers, I thought each magnet was in separate container, but low and behold there are 5 magnets in each container! So after this is done...anyone LOCAL can PM me for a good deal, say $10 a magnet instead of $13.40, I should have enough to do 4 other Kona EVs if dual magnets are good enough (leaving me a few spares in case they get lost) this will help fund the oil change

 

Thanks for that confirmation on the identical plugs.
They looked the same in @navguy12 pictures:

Drain

But I just wanted to be sure.
As it turns out, the dealer had to use my original oil change part# to order two new plugs as that is not a stocking item and there was little to no reference to them on their online manuals, 00810-17121 - the magnetic (NON magnetic) ones:

What surprised me the most was they do now stock the 70W GL4 (00232-19063) so I was able to pick those 2 up right away.
Not sure if the reason for now stocking this oil is a chain reaction from threads like these (it's all your fault @KiwiME), or if the demand is up from GDU assembly replacement regarding the TSB,
The plugs should arrive next week. I also got a discount on the oil ($50 instead of $63) as the plugs increased to $8.13 each from $4.56 original.

 

Is that because of the magnetic attraction to the steel socket or is clearance for the socket with the magnets attached the issue. I certainly don't want to cause any frustration for the mechanic at Hyundai who will be changing the oil.

 

I don't see any magnets. Is this a 2022/23 model year? Maybe Hyundai changed the plugs to real magnetic ones; if that's the case...part #s would benefit older model owners.

 

That looks like 4 magnets, good Lord...if 3 makes it difficult to work a socket, 4 might be darn near impossible.
I will also experiment when I get the ordered plugs in my hands, maybe I will have to apply them after the oil change is completed

 

If @navguy12 could chime in, maybe he could add more insight into the difficulty of magnetized socket application difficulties to tighten (or remove) the plugs. I know he used 2, maybe that is the cut-off...after all it is his original design workaround; here on in referred to as " the navguy12 external magnet technique"

 

Seeing as the neodymium magnets stick to the new plugs and by the appearance I would expect them to be fabricated of galvanized steel - coated with zinc to provide corrosion resistance.
