i just did the k&n/removal of intake resonator mod...
takes about 15 minutes, and will add more enjoyment into your life and camry (not much though)...sounds a bit richer and spreads the power band out. So if youre planning on it, giv'er, its the closest thing to getting laid for you tonight.
yeah, i got rid of the upper resonator on my 1mz, looked so stupid, this big black box just sittin there... lol, i took a spray paint can, took the black cover of it, and it made a perfect cap...
