has anyone tried the Brisk range of plugs namely the LGS premuim range, im not sure of what particular model fits the 1.8t 163bhp, they seem to get good reviews over on the us forums however for â¬45 for a set of 4 is it really worth it over NGK BKR6E 6962, on a side note do the NGK plugs also come in a v-power range suitable for the 1.8t
