i made my own
i had a cheap ebay CAI before, i got bored and made this one, i went off the Ebay one to make this, it may hurt performance with all the jagged turns but i like the fabricated look with all the welds and i doubt you could tell a HP difference on a dyno at all.
i bought the material online, i sized it to the MAF inlet and outlet so its a smooth transaction all the way through the tube. and then i layed it all out, figured out the angles and cut them up and welded them together.
i got alot of complitments on it, they ask where i got it and i tell them i made it myself they freak out.
i work at a shop that makes oil pans and valve covers so thats where i welded it up at. i am planning to make some nice looking VCs for my car sometime.
