i have a 2004 infiniti G35 sedan. the power is ok but i want it stronger and faster, i have the 6 speed. any ideas? what performance parts should i get just to get more power out of the engine?

Forget performance, instead, go to http://www.jcwhitney.com/autoparts/Store... and order the following:

Fuzzy Dice
Oga Oga horn
Yosemite Sam mud guards
Bobble head doll
Leopard skin seat covers
Steering Wheel Spinner
