Built for Performance & Reliability
The NZKW Australia Nissan RB Cylinder Head Oil Drain Kit is engineered to address one of the common oil control improvements for high-performance RB engines. During prolonged high RPM operation, oil can accumulate in the cylinder head, reducing the amount of oil available in the sump. By providing an additional external oil return path, this kit promotes faster oil drainage back to the engine, helping maintain stable oil supply and improving overall lubrication. Whether you're building a drift car, drag car, or circuit weapon, this upgrade is designed to support reliable engine performance under demanding conditions.
