Vacuum Hose Sizes

[5ky-lin3]

Hey guys,

Just wondering what the differences are on the different vacuum hose sizes? is bigger better? etc. Also what are the stock r33 gtst vacuum hose sizes?

Cheers

Furthermore,

Im currently installing my intercooler (currently keeping the stock boost pressures in place) so I need to purchase some new vacuum hose lines to connect onto the stock 'T' piece to the intercooler (or plenum). But am unsure on what internal size I will need so it will still fit on the stock 'T' piece?

I got 3 different sizes, 3mm, 5mm and 6mm. But that was to replace all my boost/vac lines. But anyways that will sort you out if you want to do the lot

yeh and the aftermarket coloured silicone vac hose is pretty stretchy too so if its a bit smaller you should be right
