Iridium sparkplug question

Would like to ask for comments from people who had experience using Iridium plugs in a 1.8t. What specific plug is applicable in my engine (1.8t A4)? Thanks.

Have em, like em. More smooth power delivery, but no more power on my ***-O-Meter.

Gap em to .040 for an unchipped car and .036 or .032 for a chipped car.

ik20

if you have a bigger turbo or are boosting more than a chip, get the ik22's

they should be gapped @ .032

NGK Irdium VX's. Much smoother running. Stock #6420 I believe.
