Unreal intake manifold cost

3. That's a tough one to answer for sure but if you aren't trying to make a business selling them I imagine companies would have a REALLY hard time trying to enforce or even claim copyright infringement especially if the manifold you make has no company logos or brand markings on them. It's just a plenum and a bunch of tubes in a fancy configuration you can't really patent or copyright that.

It's very possible to get sued for copying a part. It's not just copyright and patents. Even for personal use items. It's not common, but still a risk.

Besides, why copy a manifold when we all know most of them need tweaked to work best on a given engine? Would be far better to design any new manifold, especially small qty stuff, with geometry that's closer to what one actually wants.

Why knock off a performer when you could do an LA pattern pro dominator tunnel ram?
