Hello everyone I just bought my first Lexus about 1 week ago. Its a 2005 IS 300 and I love it! I kind of want to do some modifications, i was thinking maybe a cold air intake to start. I wanted to see what you all thought would be a good place to start for modifications, whether an air intake is a good idea and if so which one? Or if there is something else you think i should do first. This is my first time messing around with modifying a car. Thank you.
