So i got my Injen CAI the other day, and realized that it didnt have the 3.5 to 3.75 intake coupler. I contacted customer support at autoanything, but because i didnt want to wait, i found a replacement online and had it shipped. Now I see that im missing the hose that is supposed to go from the crankcase hardline to the intake tube. I can use any vacuum hose with clamps for that? Cant I?

 

Sure I do not see why not, but I would personally just have customer service ship me all the correct parts that are missing. Why pay for more stuff that you al ready paid for.
