Has anyone tried running these Denso Iridium plugs in their 2.1?

I read so many threads and suggestions on plug options for the Vanagon, as
Bosch seems to have discontinued their plugs.

I'm due for a change out of my plugs in my 2.1l motor and have noted some
concerns with the NGK 4 prongs being too deep into the motor, and the life
of other plugs seem short.

Open to suggestions or a good plug!

Thanks,

Jack R.
