The Mazda 3 Vacuum Pump provides a consistent negative pressure, which improves braking response and drives essential engine control, providing drivers a comfortable and effective ride. The unit is built on a proven four-generation history of the iconic model, having earned a reputation of being as reliable as a rock because it is mounted in an enclosed housing, lubricated with engine oil, and insulated as an electric module to prevent wear when engine demand is low. It provides about 12 psi of suction to the brake booster, HVAC blend doors, turbo vanes and emissions valves, so each time the pedal is pressed, it is smooth and each climate change is instant, even when the throttle plate is fully open and natural manifold vacuum is lost. The ability to fit early piston designs on the first Mazda 3, the subsequent rotary vane installations on the Skyactiv models and the recent tandem fuel-vacuum installations means the pump can be installed without any difficulties in any of the petrol, diesel and turbo versions. Another effect on drivers is the increased fuel efficiency, as the electric unit draws power only when sensors demand it, saving horsepower when cruising. The benefits in terms of safety are equally evident, as a healthy Vacuum Pump prevents the elusive hard pedal, increases stopping range and aids the engine in achieving the emissions thresholds. The small size allows Mazda to free up space for its KODO styling elements and for lighter-weight suspension components, which adds to the handling equilibrium that the model line is known to have. The Vacuum Pump has a hardened rotor, high-quality gears and seals that are resistant to temperature, which make the pump highly durable, allowing owners to record high mileage without fear of wear. This minor, yet crucial element, provides Mazda 3 drivers with greater stops, easier operation and confidence.
