Rallytech are a company based in Thailand offering a selection of parts for Subarus. I managed to bag a header (coolant) tank spacer kit from them, so here’s a couple of quick snaps.
Rallytech claim this kit reduces intake temperatures by moving the header tank away from the inlet manifold. Can’t argue with the logic there!
Whether I’d ever notice any performance differences in the real world commute to work and back is negligible.
But in short: looks smart, easy to fit and relatively cheap. A nice easy mod!
