The Pwrhaus MK4 SMIC Kit is the the most direct and simple way to lower intake air temperatures on your MK4 1.8T or ALH TDI.
This direct replacement bar-and-plate style SMIC offers increased surface area and more volume for vastly improved cooling performance with minimal pressure drop. With its precise welds, cast and sand blasted end-tanks, this SMIC is strong enough to handle anything you can throw at it.
Multi-map sensor fittings - for both small and large sensors - removes the guess work and allows for a trouble free installation on any MK4 1.8T or ALH TDI vehicle.
