Sorry to hijack your thread mate but would this be the best option for mine considering the mods i have, i have read some where that there is a cooler version of this plug (Colder not more hip) but cant find anything about them now.

Cheers Mate, i think with the mods you have we need the cooler plug as the ones mentioned above are the standard plug for the 180 cupra, and are what i replaced with the ones i have now which i cant remember what they are called but i have read that the ceramic bit can crack and fall of into the cylinder, not good

I cant recommend which plug type (iridiums etc) to put in (I've gone NGK Iridiums in a cooler grade myself, but based on other members feedback only) but if PFR6Q is the standard then PFR7Q is one grade cooler. The '6' in code is the heat grade and increases with each cooler grade. This is the case for NGKs, but with other makes, I've read the numbering can be the other way round, so have a look incase you dont get NGKs

The ceramic bit will only fall off into the cylinder once spark plug has been removed, could always blow compressed air into the cavity where the pencil coil sits to blow out any debris before spark plug is removed, but in the cylinder its only the threaded bit which goes in, and the tip which is actually sat inside the cylinder

NGK double platinums, are supposed to b very good. I've been advised to use them by totalVAG

Very true, i couldn't remember what bit it was but as you very kindly pointed out its impossible for the ceramic bit to fall in but a bit has been known to fall off them and into the cylinder while the car is running, killing the piston. They are Denso Iridiums by the way.
