The JDY MAC Valve Line Kit is engineered to deliver the most reliable, responsive, and heat-resistant boost control solution for high-performance JDY EA855 turbo systems. Built for extreme environments, this hard-pipe kit eliminates the weaknesses of traditional rubber or nylon lines, ensuring consistent wastegate actuation under the most demanding boost conditions.

Most aftermarket boost control setups rely on rubber or nylon vacuum lines, which are prone to failure under heat and pressure over time. The JDY MAC Valve Line Kit solves this problem with an all-metal, heat-resistant solution that keeps your boost control system precise and reliable, even at 1000+ HP levels.
