3.5mm silicon vacuum hose

[Goran]

I thought some of my vac hoses needed replacing, so I bought this stuff from Baker in the States. It turns out my hoses were ok, although the rubber has started to go soft in places where it touches hot aluminium parts of the engine, its going to go soon.

The Baker stuff is really good, very thick walls, bad pic but its over 8mm diameter overall, and inside is 3.5mm same as stock. No way is this stuff going to collapse like some of the cheap silicon hosing out there. I'll be replacing mine soon.

Audi hose is £12 per metre for standard, or £18 per metre for reinforced diesel hose, but both are still rubber.
