Intake air hose on my Camry broke, so I ordered a new Dorman one. There's a resonator box underneath it with a hose that goes to it, the hose had a hole. I couldn't find an aftermarket replacement hose, so I called the dealership. They want $76 plus tax for the hose. Not gonna happen for a beater-commuter car. I went to Home Depot and bought a 1-1/4" plug and a hose clamp for $3, fits perfect. Took out the resonator box, is it really necessary? What does it do, I'm guessing sound dampening? I drove it around the block, power is the same and so is sound, maybe a tiny bit louder, but I really don't think so.
