Bought some plugs today at short notice and from (dare I say it, Halfords). They listed the NGK Platinums for my car specifically and then they were in a pack of 4. So I had to buy 2 packs @ £39;99 a pack. Surely if they make a plug for a specific car and it's a 6 pot, they should come in 6's. As you can probably tell, i'm a bit romfed.
