Manifolds, which optimize engine airflow and form the foundation of performance, are perfected by PROSAK engineering. Manufactured using aluminum casting and CNC machining technology, our manifolds offer high durability and precise dimensional tolerances. Thanks to Finite Element Analysis (FEA) applied during the design phase, each product is tested for maximum efficiency and reliability before moving to prototype production. Whether for daily use or high-performance driving, PROSAK manifolds maximize your vehicle's potential.
