My Z was stock until I replaced OEM oil filter with K&N and OEM air filters. I also bought an akebono brake kit with red calipers. I also just had a Stillen CBE installed yesterday (and I love it!!). My unmodded Z days are over. Next: Stillen Gen 3s, new wheels, alpine HU with touch screen for ipod controls and some JL amps a small sub. I'll do suspension after I settle on what new wheels and tires I want.
