308 gti spark plugs

Hi
Just bought a 308 gti and want to change the plugs but can't find a part number anywhere, anyone know where to get them or is it dealer only?
Cheers

Cheers for the info, I looked at comkotes but the plug they sell is heat range 7, isn't it supposed to be 8?
Track day definitely on the cards!
Does anyone know where the dump valve is located?
Cheers

I've emailed comkotes to check, might be a typo...
Robins and day want 22 each!
Good find on the euro store, cheapest so far!

Quick update, got this response from comkotes which explains things, just ordered a set.

The heat range on the plugs are widely incorrectly listed as NGK do not make a heat range 8 that is of same plug gap, what happened years ago is they changed the coding system so some list them as a heat range 8, you couldnt get a NGK heat range 8 and then gap them within safety since you need a 0.7mm gap and the heat range 8 come with a 0.9mm yet NGK recommend that a plug gap should only be changed by 0.1mm, hope this clears it up. If you need to know we have heat range 7 plugs working fine on 450hp applications.Youll probably find the code you have described is listed for RCZ-R by non UK company's , that plug is not in the NGK parts catalougue and never has been.
