Precision aluminum turn part for closing the noise amplifier in the vehicle interior: After modifications to the turbocharger or exhaust system, the noise in the engine compartment is often so loud that it becomes too loud through the resonance pipes of the noise amplifier in the interior. This noise can be significantly reduced by installing the noise amplifier fix.
For installation, the blind plug is simply put on the acoustic pipe in the splashback. In case of disassembly, the plug can also be easily removed with the help of a screw. This screw is not delivered.
