This is the perfect drop-in replacement. The fully divided pulse manifold, made from high-silicon ductile iron, is designed to withstand extreme temperatures and vibration. It is designed using modern technology to ensure optimal internal geometry. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increases manifold longevity. This kit comes with new gaskets, bolts, and spacers for maximum convenience and value.
