This upgrade aims to unlock the full potential of the 4.0L Biturbo engine, delivering substantial gains, especially in the upper RPM range. This turbo upgrade features a 100% bolt-on design, simplifying installation by utilizing original oil and coolant lines. The product is compatible with stock, W.3, and W.4 turbos, and also works with stock charge piping. It is constructed with materials that include carbon fiber components, contributing to its performance and aesthetic appeal.
