That looks good
Are you thinking to upgrade the exhaust as well?
Intake + exhaust + Iridium/platinum spark plugs, bigger injector (if u dont care about mileage) + ecu Re-map + tyres.
If you want to pimp you ride go for
"carbon fibre interior lining (you can do it yourself ) aftermarket seats (or just covers), nice music system
new performance light wheels and coilovers for the ride quality but then its gona be too much i guess
