the only propper blue hose is the one from the air box to the throttle body, the rest is either this blue plastic stuff that goes over wires, or in some cases, they are hoses wrapped in tape as you cant get a propper hose kit for a ka.

samco and sfs sell silicone tape to wrap the hoses in but its £10 for 3m, just use blue electrical tape, exactly the safe effect and a dam sight cheaper.

thanks for the comments people.

just made a quick video as well, didnt thrash it too much but you can hear the revs pick up a fair bit quicker when i did, also gives you a rough idea of where the cam picks up best.
