Hi all, I'm looking to replace my coilpacks on my unmolested s3 8v 2015 saloon, unsure whether to stick with stock or upgrade, so I've read that bremi or eldor are audi items, I've been told at arnold clark that Hitachi are audi (dont trust them though). So if I'm upgrading any feedback k would be brilliant, I've got double platinum plugs in hand but want to do both together.
