Description

This is the updated design from my older cold air intake published elsewhere. Significantly better flow, CFD says it will outflow a typical 90 degree elbow. Included are two files, one with a shell thickness of 1.2mm and another with just a skin that can be shelled to whatever wall thickness is needed. For clearance, do not expand the skin more than .5mm. This design was intended for a thin wall thickness. Engine bay heat soak can causes the part to see very high temps. Enough that PLA is a non starter, and ABS is marginal. My plan was to print these with a 1.2mm nozzle in straight polycarbonate (not one of the more easily printed PC blends)- For printing I was planning to hack together a gcode file from two sperate slice results, with the elbow side at the bottom transitioning into a vase mode print after the bend. To set this part up you will need: Assuming a MAP based aftermarket ECU you will need:.
