It's r-tech who are selling the tips What rngine code do you have? A k03 maxes at about 200bhp where as the k03s maxes at 264bhp. Cupra r fuel pump is good.For the injectors. If you have a small port head (arz,aum,auq) then bam injectors will do If you hae a agu then they don't fit so you need some other but I can never remember which ones haha Think it may be calibra reds??
You won't find it for sale anywhere. You have to ring them up. I think they just call it a k03 supersize tip Think it is similar I other tips, a bit over £100 ish
