[EDIT] Follow this link to my updated list on page 5
I've had the 2004 for a week now and so far I've done a few mods. Nothing much and in fact most of them are stolen from my 97, but they are mods never the less. Here's a list:
Fumoto plug (stolen from my 97)
Synth Engine Oil (temporarily Mobile One w/Amsoil filter, will eventually be all Amsoil) Engine sounds really smooth now.
Front tower brace (generic and stolen from my 97)
Door edge guards
Deep cycle dry battery (NAPA Optima ripoff and stolen from my 97)
Yakima rack, bike trays, and fairing (stolen from my 97)
[EDIT 4/16/07] Rear gate bar (BACK ORDERED, SOA won't be making them any more)
[EDIT] Compass/auto-dimming mirror
[EDIT 4/16/07] Primitive rear (differential) skid plate
The next two lists are a tally of the mods I'm interested in so far.
PLANNED MODS (before winter):
Front aluminium underguard
All weather rubber mats
Braided brake lines and slotted disks
Optima deep cycle battery (yellow top)
PLANNED MODS (by the next summer I hope):
Whitline front and rear sways and upgraded bushings
PIAA 520s and maybe a push bar by Rally Innovations
Upgraded stereo and speakers (iPod interface, blue tooth, NAV, CD, mp3, AM/FM, mobile phone muting, tweeters, etc…)
Mobile phone repeater
Feel free to comment or make suggestions, however money IS an object... somewhat.
