Question

Quizplus · Accepted Answer

Both technicians are correct. The engine breathes through the intake system where air is pulled in before being mixed with fuel for combustion. The exhaust system then allows the byproducts of combustion to exit the engine. Any restriction in either system will negatively affect engine performance as it will limit the amount of air or exhaust that can flow through the engine.
