the blue lights are garbage,so is the intake
For an intake look up BFI, basic modifications to what you have already for maximum output.
GPS i would go with a new radio like the pioneer avnc N1 or N2
for lots of options like dvd and a full screen with GPS as well .
If your dash is broken then get Jim to fix it.
Tires ,their is no balance for all 3 things,
For performance it wears faster and costs more
for durability it is cheaper ,noisier and has low traction
All season well then everything is out the door.
Get a set of winters and summers ,their is no comparision to it.
