Cold Side Turbo Builder Kit 3"- 4"

Save yourself shipping and guessing, this cold side kit has everything you need! This kit has enough bends to do most turbo kits without coming back for more. One of the keys to building a rock solid turbo kit is to NOT use angled silicone couplers. These couplers open up the door for large surface area for boost to push against and burst.

Included in this kit is all American material and bent bends. Choose which diameter tubing you would like from 3" , 3.5", or 4".
