We’re developing a CNC-machined billet aluminum intake manifold spacer for the Hyundai/Kia 1.6T platform. The design combines a dedicated water/methanol injection (WMI) port for each cylinder with a manifold-to-cylinder-head transition shaped around the port geometry.
This is a prototype development update. Final engine and vehicle fitment, nozzle specifications, included components, pricing, and availability are still to be confirmed.
Four cylinders, four planned injection ports
Our design places a WMI port at each intake runner. This gives us separate nozzle locations to evaluate during development instead of relying solely on a single upstream injection point.
More consistent cylinder-to-cylinder delivery is a design goal. Nozzle sizing, placement, flow, and calibration will need to be tested before we can make performance claims for this spacer.
Developing the port transition
We’re also working on the transition between the intake manifold and cylinder head. The aim is to match the relevant port geometry and evaluate how the finished spacer affects the intake path.
Billet machining lets us refine port dimensions, nozzle position and angle, sealing surfaces, and material thickness as the design develops.
Testing comes next
Our planned evaluation includes flow testing, datalogging, intake-temperature and knock-response monitoring, and dyno testing on our shop car. These are development steps, not completed test results.
We’ll share measured findings as they become available. We are not announcing a verified horsepower gain, temperature reduction, or improvement in WMI distribution at this stage.
Build requirements
Water/methanol injection requires appropriate nozzle sizing, system safeguards, and ECU calibration. Final installation and compatibility requirements will accompany the finished product. Off-road or competition use applies where required.
