[QUOTE="keep_hope_alive, post: 8869215, member: 576029"] After the noise treatments in the doors, floor, and rear of the Camaro, I turned my attention to the firewall. These vehicles have a tube that runs from the engine intake pathway to the firewall, with a diaphragm to isolate airspace but allow sound to pass through. The solution is to 3D print two pieces that let you plug each of the holes – one at the firewall and one at the intake pathway, just before the throttle body. I printed these out of ABS. The fire wall connection looks like this, with a 10mm nut: [ATTACH=full]56288[/ATTACH] [ATTACH=full]56289[/ATTACH] [img]https://hosting.photobucket.com/images/e128/phat_funky_beats/20240124_211949.jpg[img] [ATTACH=full]56290[/ATTACH] The hose connection at the intake pathway looks like this: [ATTACH=full]56291[/ATTACH] And the rubber hose clamps are easily opened and removed as they just use push-clips. [ATTACH=full]56292[/ATTACH] The diaphragm is held with T50 Torx bolts: [ATTACH=full]56293[/ATTACH] With the hose removed, you have this: [ATTACH=full]56294[/ATTACH] The result at the firewall is this piece with butyl gasketing: [ATTACH=full]56295[/ATTACH] The result at the intake pathway is this plug that fits perfectly: [ATTACH=full]56296[/ATTACH] The result is very noticeable. All of the intake noise is gone. The chugging noise from V4 mode is gone. The cabin is much more comfortable.[/img] [/QUOTE]
