The Mitsubishi throttle body spacer has its roots on the racetrack, where it originated as a power booster for racecars. Through the years, the airflow concepts came to be used in street vehicles, with a Mitsubishi throttle body spacer being able to add up to 20 horsepower to your vehicle, depending on make and model. Vehicles that have already had other engine and power modifications can sometimes gain even more horsepower with the addition of a Mitsubishi throttle body spacer. A Mitsubishi throttle body spacer is installed right between the throttle body and the cold air intake, and increases the space between those two parts. The purpose of that is to give a little extra room, which allows the air to be compressed and cooled a bit more, as well as have its flow speeded up by the inner design of the Mitsubishi throttle body spacer. This is an affordable improvement, and in addition to boosting the power that your engine produces, the Mitsubishi throttle body spacer can improve your fuel mileage, as well, by setting the stage for a more efficient use of fuel. The vehicle's computer registers the increased flow of air provided by the Mitsubishi throttle body spacer and adjusts the flow of fuel to achieve the best air-to-fuel ratio. This increased efficiency means that you won't be paying more at the fuel pump for the increase in horsepower and performance provided by the Mitsubishi throttle body spacer. We offer an affordably priced Mitsubishi throttle body spacer selection through our online catalog that is broad enough to ensure that you'll probably be able to find one that is just right for your year and model.
