legal boost for a 1.4 in cali (2020)

Hello everyone i hope we are all doing great! so i live in California and own a 2015 1.4 cruze. the only thing i have done so far is give it an air intake that makes it sound so much more fun to drive. but now i actually want to make more power from it so i was wondering is there anything i can do to make my car faster and still be able to keep it legal? as much as i want to buy everything from carid and zzp i need my car to pass smog since i use it to drive the family and all. please if anyone can help me out that would be great!!
