I have about 210 HP with chip, larger intake pipe, turbo back exhaust without cat, forge 007p...etc.
I was told that the NGK Laser Platinum from Audi TT are good. Part number is 101 000 063 AA.
I don't want to pay extreme for the plugs, but I want a good one for my engine setup and that is aprox. 210 - 220 HP.
This one should be for 225HP.
What do you thing, do you recomend something else?

I would have thought that, because of the extent of the tuning on the 1.8T's, especially yours upped by 60+bhp, that you would need the platinum tipped, which will cost a bit...
NGK's are good plugs, and so you could give those TT ones a go?

Any decent plug should do.
All these new 'wonder-plugs' are nothing new. After all what's the point of it being platinum tipped anyway? It'll take about 100 miles for the deposits on the plug tip to be deeper than the 'platinum coating'.
Don't skimp, but don't be fooled that your gonna get super performance from a 'bling bling' plug either.

I have put in the NGK laser platinum ones and I cant say that i can tell the difference. I have heard from a seat mechanic that they are not that good and suggested I changed them for DENSO Iridum plugs... :confused:

I'm going to go for Cobalt-Deuterium-Dilithium-Gold Pressed Latinum plugs...I need them to generate the extra power to pull away from the Ferengi :p

I know it does matter what plugs you go for wrt heat. but I'm not on top of that.
I'll see if I can read up some

bascially if it's not failing, don't bother. The heat is how much it can dissipate.
a spark is a spark & (from my a level physics) the 'tip' won't make any difference.

Aye. Well said :p

Platinum plugs are for extended service intervals, not performance. VW upped the plug change interval on the VR6 from 20K miles to 40K miles when they started specifying platinums. The daft thing was/is that two sets of the non-platinum version were/are cheaper than one set of the platinums. Of course, Joe Public doesn't know this and it's not unheard of for some VW dealers to change the Platinums every 20K @ £120 a set.....
The other advantage of platinums on a VR6 is if you have a Schrick VGI manifold, you have to remove it in order to change the plugs so only having to swap every 40K = lower labour charge or less p!ssing about if you DIY. I prefer to change every 20K and use the non-platinums.
AQX engine is 40K interval according to my service booklet and I'd expect all 20VT engines to use platinums as standard.

Always worth checking your plug gap though - one time we checked them on my mother's Rover, with 25k on the clock (and a plug change at about 40k I think it was...), the plug gap was almost 3 times what it should be... and yes, we were having difficulty starting the engine, and it did run bad... Annual changes now regardless!
