Laser Tools part number 6298 is equivalent to VW Group tool T10530 - I can confirm that from the packaging! Though normally on the Laser Tools site it does also show details of the packaging.

Yes, it also says that on Laser Tools' PDF technical description, which I downloaded a few days ago. But it might not be an exact replica. Other suppliers, eg. BGS (Germany), market a version that's also reckoned to be equivalent to the T10530. However, the BGS version has an additional piece to it that appears to give you more of a squeezing action than a pulling action and which would probably make the job easier.
Quite aside from this, there's a question as to whether the one you select as a potential buy is going to definitely have a minimum expandable-bolt diameter that'll fit into the coilpack hole. If that diameter turns out to be too big, the tool will be useless, as you won't be able to initially get it into the hole. In that regard, some of these T10530 claimed-equivalents could well be suitable for Golfs, Audis, Skodas of a few years ago but might not be okay for the coilpacks fitted on current or near-current Polos. On this score, I'm making enquiries with one or two suppliers.
It'd be helpful perhaps to see an engineering sketch or photo of the VW T10530 tool taken from the 'workshop repair information' to which iichel referred near the beginning of this Topic.

Fair enough, that the passages that someone copied and pasted from the official VW workshop manuals, did specify this very tool, so that is good enough for me.

Top connection style: cup.
Electrode gap: 0.7 - 0.8 mm.
Recommended maximum torque (Al head): 23 Nm (~14.5 lbft).

An update:
It's been confirmed that the OEM version of this sparkplug, as fitted to this particular vehicle, is the 04E 905 601B (note the B). This is the NGK plug that's simply been rebadged for Volkswagen AG.
For anyone wanting to inspect or change their plugs for whatever reason and who therefore wish to undertake this job, it should be understood that you'll need an extra-long sparkplug socket, as the plugs are very deeply recessed. But don't risk using extenders. The Laser 3682 or the Sealey AK 6552, both around 250mm long, are good candidates and although quite expensive can be bought from various sellers on Amazon and elsewhere. A puller tool for the coilpacks, such as the BGS 4032 (based on the OEM tool T10530), can also prove useful, though in most cases may not be absolutely necessary. Again, this is quite an expensive tool. Note that previous pullers, such as the Draper 23254, are totally useless for the kinds of coilpacks now fitted.
It's not necessary to disconnect the low-tension wiring that feeds the coilpack. The connectors associated with this wiring are, in any event, extremely difficult to take off, unless you've the appropriate tool. For plug nos. 3 and 4, the air ducting over their coilpacks will need to be temporarily removed, though this shouldn't prove difficult. Ensure that the sparkplug socket fully engages on to the sparkplug nut before attempting to undo the plug; the same applies when tightening it. Above all, use a good-quality socket (16mm) - if the fit on the nut is either overtight or sloppy, you could end up with the nut's flats rounded off and then not being able to proceed any further or, worse still, the socket cold-welded to the plug and it permanently stuck in the sparkplug recess. Tighten the plug to no more than 14.5 lbft.
Returning to the matter of purchasing one or more new sparkplugs for the 2014 - 2017 yr Polos, be careful when shopping around that you pick the precise one required for your engine. I've seen from a downloaded NGK catalogue that the NGK PZKER7A8EGS was introduced by NGK around April 2014 and that the VAG Group itself fits the NGK one as OEM no. 04E 905 601B. The straightforward 04E 905 601 is not the same, I think. The B version is a 'longlife' type. I think you can confirm this on the nemiga website. This might explain why the B versions are particularly expensive. But a word of caution: when you see the Bosch or NGK ones advertised on the Web, you cannot always be certain that the seller has got the OEM equivalence correct. So, what you could end up with is the Bosch or NGK equivalent of the 04E 905 601, rather than of the B version. In the end, to avoid this possibility it might be better to just buy them from the VW dealer (quoting your VIN no.), though of course that's down to personal choice.
