Make TOPRAN

The TOPRAN 118 931 Secondary Air Injection Pump is engineered to meet the demanding requirements of modern vehicles. Its primary function is to inject air into the exhaust system during cold starts, promoting a more complete combustion of fuel and significantly reducing emissions of pollutants like hydrocarbons and carbon monoxide. This component is vital for the proper functioning of your vehicle's emissions control system. By ensuring that the catalytic converter reaches its optimal operating temperature more quickly, it helps to minimize the environmental impact of your vehicle, especially during the initial warm-up phase. Crafted with durable materials, the TOPRAN 118 931 is built for longevity and reliable performance. Proper installation and maintenance of this part will contribute to smoother engine operation and compliance with environmental regulations.
