The JRspec cast iron collector is designed for 1.8T 20V engines in VAG vehicles, featuring a T3 turbo flange and waste gate outlet. Constructed from high-quality cast iron, these collectors have enlarged channels to enhance exhaust gas flow and are annealed to prevent cracking. The collector flanges are precisely arranged, ensuring it is ready for immediate installation.

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