Nearly half of all new cars made today use forced induction or ‘boost’ - this means they use superchargers, turbos or sometimes, both together. There’s a reason every major manufacturer now offer turbocharged or supercharged variants; boost improves efficiency, reduces the engine displacement size, improves packaging and increases horsepower and torque. In the aftermarket, one of the best ways to get the most bang for your buck is with turbocharger or supercharger kits and bolt on accessories like intercoolers, larger downpipes, and boost controllers.
