There isn't any real intake mod available for the 2003 /4 model years that we know of. Plus, if you change the stock air filter for the K&N, you will probably cause problems with engine performance (MAF fouling, etc.)!
Frankly, this is one car that does just fine in stock form! Just keep it in good performance shape, and it will treat you just fine with its combination of power and luxury!
