I was speaking to a guy at SFS who claimed some significant gains on their 130bhp Golf with the fitment of a silicone hose kit. They don't however do one for the 130 in the Audi. I've been digging around without much look. Has anyone else found kits for the 130 in an A4?
I could get them made up but for that I would need a group buy of 20 people and a spare set of hoses to copy off which I don't think is likely
