Absolutely love this intake on my 04 4runner, great noise under load and silent while cruising at low load and seemingly better mpg with my heavier tires. My setup seems to be quite rattely at peak torque but I put a few personal touches with the factory side scoop that could be the issue. The box and intake are two separate pieces, the intake sort of hovers in the box. Slightly worries the water concious driver in me. Also sits very close to the radiator fan.
