I am contemplating to get 1.6 SX but is also looking forward to do the below minor changes. Will it void the warranty and if yes which part will be affected? Thanks in advance for enlightening me

1) changing rims to 16"
2) changing to iridium spark plug
3) changing knn drop in filter
4) ground cabling with volt stabilizer
5) adding in a 4ch amp (no idea on the Hi-Lo yet)
6) changing the speakers for SQ purpose
7) adding UR front strut bar
8) changing the crank pulley to a lightened CP
