-Improved throttle response, increased torque and greater fuel efficiency. -Increased reliability and decreased engine temperatures at low RPM. -Prevents carbon particulates from the exhaust system from clogging up the inlet manifold. -The full exhaust gas flow now spins the turbo blades, delivering faster spooling up. -Vacuum and boost lines remain clean and unobstructed by carbon particles. -Engine oil remains cleaner for longer because a lower volume of carbon particles can make their way into the oil system. -The engine runs much smoother and delivers more torque at the lower RPM where the EGR is usually f Functioning.
