New Ignition Coils
 

Been planning on changing the plugs for a while, and since its on the orginal coils at 137k I figured I'd do those to,

Any recommendations or ones to avoid?

I assume these should be ok?

If the ignition coils are working fine, there's no real need to replace them. They'll generate misfire codes when they fail.
However, I would trust an NGK replacement just fine.
48082 is the correct coil for the 5V 4.2.

Genuine Audi coils at FCP Euro are US$40 ea. I thought they were Bosch, but I cannot find an Audi coil in the Bosch catalogue, so I have no other brand suggestions.

If you stick with NGK, same coil at a lower price here

revisiting this. just got around to replacing all 8 at a very reasonable £157 delivered from https://www.gsparkplug.com/

much smoother start/idle and running feels like I've found 20bhp

though I will concede that cylinder 7 had a slightly loose plug which may not have helped matters
