There is this "custom aftermarket bracket" mentioned. Fabspeed sells this: https://www.fabspeed.com/fabspeed-porsche-911-turbo-930-air-intake-system-1976-1989/
but that kit seems a bit overpriced. (unless someone can convince me it's worth the price)

I just bought a RU-5163, will arrive tomorrow. The correct flange diameter and height for clearance. Tired of the breadbox taking up all that room. No bracket needed, comes with a 5 inch hose clamp. $53. You can buy those small filters elsewhere for maybe $20 a pop.
