Pros: OEM or Denso recommended
Cons: cheap aftermarket junk

Or since Denso is the OEM, you could get a remanufactured one at [NAPA](https://www.napaonline.com/en/p/DEN2105000) or [RockAuto](https://www.rockauto.com/en/parts/denso,2105000,alternator+/+generator,2412), but it looks like they're out of stock. I would not trust the cheaper remanufactured ones that are made by the other brands. Denso is reliable, and I'd trust their reman parts, if you decide to go the reman route.
Pros: Denso is reliable
Cons: cheaper ones untrustworthy
Part number: 2105000
But try to get denso one or oem. Aftermarket ones tend to not last a long time.
Pros: oem parts last longer
Cons: aftermarket ones fail

The Denso IHKs are my go to for the last 10k on their tune.
Pros: reliable, good performance
Cons: gapping info mixed
Mileage: 10000 km
Either one, but I found the Denso to be cheaper and easier to get. No issues with them.
Pros: cheaper, easy to get
Cons: none

I ordered a new denso online then had a mobile mechanic come install it for me in my garage.

You can usually find DENSO IRIDIUM Spark Plugs , which are the OEM Supplier, for about $15 each at any Advance Auto or other major auto parts store.
Pros: easy to find, oem supplier
No discernible difference to me, positive or negative. But since I am running APR stage 1, I followed APR's recommendation.
Vehicle:
Volkswagen
I had EPC light/limp mode and P303 as well about a month ago on my '12 GLI (APR Stage 1+) at 102K miles that recently had a walnut blast and new Denso plugs at around 101K miles. Swapped coil packs as well and still P303 with EPC light/limp mode.
Cons: catastrophic failure
