This is the exhaust gas recirculation (EGR) valve flange blocking plug and blanking plate (заглушка ЕГР), custom-engineered for Renault Megane 3 models. Designed to sit perfectly flush against the original manifold or EGR pipe connection aperture, this retainer plate ensures the port is tightly sealed without chafing or wearing against raw metal panel edges. (Note: If placed on the high-heat exhaust side, metal production or CNC fabrication is required; high-temp engineering filaments should only be used for intake/low-temp block-offs).

Print Recommendations:Material: Nylon (PA), PEEK, or Carbon Fiber reinforced filaments (High exhaust gas temperatures and chemical exposure require advanced engineering materials; standard plastics WILL MELT)Layer height: 0.12mm to 0.16mm (Low layer height recommended for optimal mating surface flatness and sealing)Infill: 100% (Solid infill is mandatory to prevent gas pressure bypass and ensure a non-porous structure)Supports: may vary depending on the model orientation and print bed direction. Please consider your slicer's recommendations
