What are positive impact of western culture on indians?
Do you mean Native Americans? That is the correct political term for them. Indian is the correct political term regarding natives to India.
Do you also mean the Europeans? Because the Native Americans WERE the Western Civilization until the Europeans migrated over.
There are a few things. The Europeans brought over a lot of things that they didn't have before like horses. That changed their lives greatly, allowing them to hunt buffalo better, to migrate more easily, etc. But also all kinds of trade goods--dishes, pots and pans, hairbrushes, clothes, tools, even guns.

There are more negative effects though.
