Investment Cast Stainless Steel Turbo Manifold

The Treadstone M158 turbo manifold represents a significant advancement in turbocharging technology, building on Treadstone's pioneering work with cast stainless steel manifolds introduced in 2006. This specific manifold is engineered for the Nissan Sentra Spec V SER and Altima models equipped with the QR25DE engine. Constructed from 347 investment cast stainless steel, the M158 offers advantages over traditional tubular manifolds. Its high thermal inertia and excellent heat retention help to deliver more thermal energy to the turbocharger, thereby increasing system efficiency. The material choice also prevents the rusting commonly seen on cast iron manifolds, ensuring a cleaner aesthetic and longer lifespan. Treadstone backs this durability with a lifetime warranty against cracking. Precision-machined mating surfaces are incorporated to ensure a perfect fit and reliable seal, critical for managing exhaust gases effectively. This focus on precision contributes to high exhaust gas energy, which translates to optimal turbocharger performance. The manifold utilizes a 1.25" thread pitch for its connections. This turbo manifold is designed to fit 2002 to 2010 Nissan Sentra and Altima vehicles equipped with the 4-cylinder QR25DE engine.
