Double Iridium Spark Plugs - Worth it?

[2020 CX5 Ow]

I have a 2020 Mazda CX-5 GT naturally aspirated engine.

I'm wondering what people's thoughts are on getting some double iridium spark plugs. I can't believe how much cheaper they are vs. OEM, and supposedly higher quality.

Thoughts? For example, I found the following:

BOSCH 9621 OE Fine Wire Double Iridium Spark Plug​

The entire set of 4 is the same price as a singular Mazda Genuine OEM plug. Blows my mind.

I just replaced my plugs on my 2023 CX5 turbo at 39000 miles....I went OEM via Mazda Swag it was like $108 which seemed high but in reality the old plugs looked new so next time I will stretch it out a bit longer than the recommended 40,000 miles and I figure $108 every two or 2.5 years for something so easy to change is no big deal...I have already forgot about the $108.

Not a fan of the Bosch. I use NGK (preferably) or Denso.
