Spark Plugs - Does anyone use Denso?

I was just wondering if anyone on the forum is using Denso IKH20 iridium spark plugs on their Liberty GT 2.0L Turbo?
They have a factory gap of 1.11mm
My car was fitted with these by the mechanic and I was wondering if anyone has them fitted also and if there are any issues with them?
