Q: It's an 01 RX300, and it's blueish-silver with chrome 17-inch rims.
A: Put in a cold-air intake for about $200 to get you about 5 extra HP, but you'll lose the quietness. A more free breathing exhuast for another $150 or so to get another 3-10 hp perhaps. Again, all of these add noise because it'll start sounding like a "fart can" car, which you may or may not want in an Lexus.
