HOFFER Secondary Air Injection is an essential component of the secondary air pump system in vehicles. It helps to reduce emissions and improve engine performance by injecting fresh air into the exhaust stream. This air is then used to facilitate the combustion of unburned fuel, resulting in cleaner exhaust emissions. The HOFFER Secondary Air Injection system includes a valve for secondary ventilation, which helps to regulate the flow of air into the system. Additionally, the system also includes a secondary air pump, which is responsible for pumping the fresh air into the exhaust stream. HOFFER offers a range of reliable and high-quality secondary air injection components, including valves and pumps, to ensure optimal performance and reduced emissions for your vehicle.
