1" and 4" carbon fiber intake tubes are precision-engineered to boost automotive performance by maximizing airflow to the engine, a critical upgrade for racing, tuning, and high-performance street vehicles. Unlike restrictive plastic or metal intake tubes, these carbon fiber variants feature a smooth, aerodynamic internal surface that minimizes air turbulence, reducing pressure drop by up to 30% and increasing volumetric efficiency. The 1" tubes are ideal for auxiliary intake systems or turbocharger intercooler pipes, while 4" tubes serve as main intake pathways for large-displacement engines or forced-induction setups. Constructed from 3K woven carbon fiber with a heat-resistant epoxy matrix, they withstand underhood temperatures up to 200°C (392°F), preventing heat soak that degrades air density. Lightweight (40-60% lighter than aluminum) and corrosion-resistant, they resist fuel vapors and road debris, ensuring long-term durability. Each tube is mandrel-bent for precise fitment, compatible with popular makes like Ford, Chevrolet, BMW, and Subaru, with flange options to match factory or aftermarket air filters and throttle bodies.
