well mate you are very much wrong, my mate has a 1.8t running 250bhp with an alltech induction kit and has been on a year now with no problems what so ever so i think it will be alright on a lupo!! but i know they do heavy duty silcone hoses but it would of cost me more but for my budget of £125!! (all in) it was a steal and not bad considering i get 6 -12bhp more !!!! and a bunch of good lads
