The Engine Parts > Intake & Exhaust category contains components vital for controlling the flow of air into and exhaust gases away from the engine in passenger cars and commercial vehicles. These parts directly impact engine performance, fuel efficiency, and emissions control. Intake systems, including air filters, intake manifolds, and throttle bodies, deliver clean air for combustion. Exhaust systems - comprising manifolds, catalytic converters, mufflers, and tailpipes - safely remove spent gases while minimizing noise and harmful pollutants. Examples within this category include Scania parts like MPN 1391499, exhaust components for Volvo Trucks, and intake manifold parts for Audi (MPN 06A253033AJ) and Volkswagen vehicles.
