Exhaust Manifold VAG 2.5 FSI - T3 Premium cast iron exhaust manifold Premium cast, perfect fit and optimal in price performance SPA cast iron exhaust manifolds are manufactured using an alloy perfectly suited for its intended use. The manifolds are engineered using sophisticated software simulating flow, mechanical and thermal stress to ensure maximum reliability and optimum performance. Additionally, prior to being sold the manifolds are tested under real driving conditions including racing sessions. This intricate process of research and development sets our headers apart from most cheaper headers which often fail to yield the expected performance and are often prone to heat cracking. All manifolds are perfectly suitable what unfortunately can not be said of many cheap manifolds. Besides the fact that this anyway tear usually after a short time or even break. So don /t save at the wrong end! A SPA manifold gives you a perfect price / performance ratio! Each manifold comes with a 1 year warranty.
