42 Draft Designs tubing kits combine the best of the best at an affordable and competitive price. In the engine bay we're tapping into the factory intercooler plumbing with a miniature brass barb. Our brass barb uses miniature threads keeping your installation compact and discrete. At the gauge we're using our straight boost gauge fitting or our 90° boost gauge fitting. These fittings are the most compact barb fittings we've ever found, allowing installation in the tightest of gauge pods. Tying it all together is 8 feet of the toughest and most flexible tubing we've ever used. Made from a high-tech polymer, our new tubing is flexible enough to bend around a quarter, but stiff enough to support itself without kinking or drooping. Our tubing can snake through gauge pods without kinking or crushing, while simultaneously holding tight on our barbed fittings without zip-ties or clamps. Spliced somewhere in-between, our proven Inline Restrictor provides a clean signal to the boost gauge. Zip ties and installation instructions are included for convenience.
