Retaining factory intake pipes, oil lines, coolant lines, manifolds and dump pipes not only reduce the chance of something failing but also allows the owner to purchase parts locally from a dealership if something were to ever fail. Aftermarket parts are sometimes hard to find and also hard to know what’s been fitted as well.
