I put in NGK PFR7B plugs and R8 coil packs. Smoothed the idle out and judging by the butt dyno the rev/boost response seems great.
Pros: smoothed the idle, great response
Part number: PFR7B

I run stock NGK with .026 gap as well and I've been anywhere from 10-18psi
Pros: works well at high boost
Vehicle:
Volkswagen
The plugs were only part of the problem. (They were NGK VW/Audi part#1010000035AB, NGK BKB5EKU. Good plugs, lasted forever. Sure, they needed to be replaced, but the #6 plug well must have been flooded a time or two before the radiator was replaced last month. The metal plug jacket had a lot of green crud in it. I cleaned the plug jacket with cylinder brushes from Harbor Freight ($7.00 without coupon for an assortment 3 sizes in SS and brass) and finished with medium emery paper wrapped around a thin long screwdriver. The motor runs smoothly now, across the RPM range, without hesitation.. I'm wearing a pretty wide smile.
Pros: good plugs, lasted forever, runs smoothly, no hesitation
Vehicle:
Volkswagen
Part number: 1010000035AB / BKB5EKU

Pros: no issues, good performance
Cons: consumption falling in cooler temps
ngk Same as prof315-jeff,bkr7eix on both setups,supercharger and now turbo and they still work,my only mishap is i bought a set bkr8 and one fouled do to much gas @ idle,now with megasquirt no problems so far.
Pros: still work, no problems
Cons: one fouled due to gas
NGK BKR7EIX is a popular plug for 1.8T and 2.0T, but it is one step colder in the heat range. Fine for those whom don't see freezing and below temps.

Cons: too cold for freezing temps
