The JRspec cast iron collector is designed for BMW engines including 2.5, 2.8, 3.0 E36/E46, and 3.2 E36 models. Crafted from high-quality cast iron, these collectors feature enlarged channels to enhance exhaust gas flow. They are annealed to prevent cracking, and the collector flanges are pre-arranged for immediate installation.

Please note that the exhaust manifold requires longer mounting pins, which are not included in the set.

T3 turbo flange compatible.
