Oooooh, a fellow modder

There are several induction kits out there. The best looking is the Carbonio as it enables you to retain the OEM engine cover, but it doesn't give quite as much power benefit as some of the full systems like Dbilas, EVOMs, Neuspeed etc. I also believe there is a group buy being set-up on another forum soon.
Quick and easy mods are numerous and it depends on whether you just want engine mods, or suspension and styling mods as well.
