A conduit used in turbocharged or supercharged internal combustion engines transfers compressed air from the turbocharger or supercharger to the intercooler or directly to the intake manifold. This component is typically constructed from metal (like aluminum or stainless steel) or durable reinforced plastic, designed to withstand elevated pressures and temperatures. Its primary function is to efficiently deliver the pressurized air, maximizing engine performance by increasing the air density entering the cylinders. An example is found in many modern high-performance vehicles where forced induction is utilized to boost horsepower.
The integrity of this delivery component is crucial for maintaining optimal engine power and efficiency. A failure, such as a crack or leak, can result in a significant loss of boost pressure, leading to reduced engine output and potentially affecting fuel economy. Historically, original equipment manufacturer (OEM) versions were often made of plastic, which could be prone to failure under the stresses of increased boost levels. Consequently, aftermarket upgrades using more robust materials are commonly sought to improve reliability and performance, especially in modified vehicles.
