I haven't found on the net other guide to do a cheap brake duct intake for cold air... So i've tryed to do my home made version with some diy...
No project, behind this job, i've improvised all. For this reason, the cutting of the 2 hubs i've made, are different. While i was cutting the left one, i've noticed that a different kind of cut, may have improved the solidity of the duct/dust cover, so the cuttng of the right one is better.
