Nice!
This is POWERCAP for the standard Opel / Vauxhall C20XE Inlet Manifold. Adding this part will result in more sensitive throttle and increased power. Inlet pipe diameter is 60 mm. This model has NO fitting. The thickness of the wall is increased for use with turbocharging. Recommended ABS (or TPU) printing, mechanical and chemical post-processing.
Feel free to write to me if you need additional variants of shape or part size for your particular variant. I will gladly complete the additional options.
Works great with this gasket https://www.cgtrader.com/3d-print-models/hobby-diy/mechanical-parts/opel-c20xe-throttle-gasket
