Show original supplier description
The ISR Performance Tubular Bottom Mount Manifold, Version 3, is engineered for the Nissan SR20DET engine, offering an enhanced solution over its predecessors. Constructed with thicker Schedule 40 Weld-El piping, this manifold is built for durability and improved performance, aiming to upgrade horsepower while maintaining reliability. It is designed as a direct replacement for OEM manifolds, simplifying installation. This manifold features stock replacement primary and collector sizes, finished in a raw state. According to the specifications, it does not require a tune after installation. However, users may need to slightly clock their T25 or T28 stock turbos to ensure clearance with the larger runners of this manifold.
