Really interesting to read that GTIreland.  My new 8.5 GTI has come on woeful Bridgestone rubbish which will be being swapped (all 4) as soon as we have the first sunshine in the spring.  I was all set to get PS4S (which I have had before and loved) but now you're making me really think about these new Pirellis - I found the PZEROs that were OEM on the two 7.5 GTI's I had were bang average and I would never have spent my own money on them - but these sound much more interesting. 

Darn will have a real decision to make now... 

No. Not needed with G12 Evo. This is for cars with G13 that originally came with the silicate bag.

To replace the silicate bag with something a) new and b) more robust. It is not designed for our water bottles but, by coincidence, clips in where the bag used to sit. It's an option if you want to remove the bag but want to avoid the inevitable coolant change required if you do as existing coolant will age quicker without the silicates.

PS, when I say new, I am referring to it being in better nick (and therefore less likely to fail) than your 10 year old bag, not that it contains anything new or fancy,

Cartridge for anyone interested
