Engine Management
Bosch Switching-Type Oxygen (O2) sensors provide precise air-fuel-ratio measurements to the ECU, ensuring stable combustion control and helping reduce emissions across a wide range of operating conditions. Evolving from the original thimble sensor Bosch pioneered in 1976, Bosch later developed planar narrowband designs that offer faster light-off, improved lambda accuracy, and quicker closed-loop operation. Using advanced ceramic elements, optimized heater control, and high-temperature-resistant materials, Bosch Oxygen (O2) sensors deliver consistent performance even under harsh thermal and vibration loads. Backed by more than five decades of OE development, Bosch supplies a full line of durable, accurate Oxygen (O2) sensors to the aftermarket with the same OE-proven quality trusted by vehicle manufacturers.
Bosch Wideband A/F Oxygen (O2) sensors provide continuous, high-precision measurements of the air-fuel ratio across the full lambda range, giving the ECU far more detailed information than traditional switching sensors. This enables exceptionally accurate air-fuel mixture control — supporting improved fuel efficiency, engine performance, and reduced emissions under all operating conditions. Bosch pioneered the first Wideband A/F Oxygen (O2) sensor, introducing the planar pump-cell design that has become the global standard for modern engine management and low-emission technologies. With fast light-off, optimized heater control, and robust ceramic construction, Bosch Wideband A/F Oxygen (O2) sensors deliver reliable performance even during rapid load changes and harsh thermal cycles. Backed by more than five decades of OE development, Bosch supplies a full line of durable, accurate Oxygen (O2) sensors to the aftermarket with the same OE-proven quality trusted by vehicle manufacturers.
Bosch SmartLink™ Universal Oxygen (O2) sensors combine OE-specification base sensors with a flexible, patented Posi-Lock® connector system designed for fast, reliable installation across a wide range of vehicles. Each sensor uses the same high-quality zirconia ceramic element and heater design found in Bosch OE applications, ensuring accurate air-fuel-ratio feedback and dependable performance. The SmartLink™ system features Posi-Lock® connectors that create secure, high-temperature & weather resistant electrical connections without the need for soldering, crimping, or specialty tools — allowing technicians to adapt the sensor to existing harnesses quickly and confidently. The extended lead length provides added flexibility for vehicles with damaged or shortened wiring, and the connector system can be reopened and reused if adjustments are needed. Engineered to provide an easy, universal installation experience, Bosch SmartLink™ Universal Oxygen (O2) sensors deliver professional-grade fit and function with the same OE-proven quality and dependability trusted by vehicle manufacturers.
Bosch Distributor Caps and Rotors are made from top quality materials throughout to ensure high performance and long product life.
All Bosch ignition coils are built to achieve or exceed OE specifications and are known industry-wide for their reliability and performance. Bosch ignition coils convert low voltage into high ignition system voltage, creating an electric spark sent to the spark plugs which ignites the fuel.
Bosch Idle Air Control Valves are made with precision engineering and are robustly designed to withstand long engine life.
Vapors are produced in the fuel tank due to external heat radiation or surplus fuel gaining heat before returning to the fuel tank. These vapors are captured and then purged by way of an activated charcoal filter. A purge valve is located between the intake manifold and charcoal canister, and is actuated to allow fresh air to be drawn in through the canister to purge the captured fuel vapors. A faulty canister purge valve will cause a check engine warning and is an emission relevant component.
Bosch Leak detection pumps ensure the evaporative emission system (EVAP) is functioning correctly. Leak detection pumps provide pressure so the system can be checked for leaks while other EVAP system valves are closed. A faulty leak detection pump will cause a check engine warning and is an emission relevant component.
Spark Plugs
Bosch Platinum+4 Spark Plugs deliver smoother acceleration, top fuel economy and ultimate engine performance. Bosch Platinum+4 Spark Plugs reach self-cleaning temperatures faster for quicker starts, smoother acceleration and increased fuel efficiency.
Filters
Bosch Cabin Air Filters are designed and tested to meet High Efficiency Particulate Air (HEPA) standards based on test standard ISO 29463-3, and provides filtration efficiency of 99.97% at 0.3 microns*. This efficiency provides ultimate protection in trapping allergens, dust and other particulates that can enter your vehicle and provides the cleanest air possible for you and your family.
Bosch Workshop Cabin Air Filters are specifically engineered for the professional installer dedicated to helping customers breathe cleaner air. Bosch Workshop Cabin Filters offer an 99%* efficiency rate at 3 microns or greater in capturing dirt, dust and other environmental contaminants from entering the heating and air vents of a vehicle.
Bosch Workshop Air Filters are designed specifically for the Professional installer market offering high vehicle coverage to ensure installers will always have the right air filter.
Bosch Fuel Filters help to protect the most expensive parts of the engine by filtering out foreign particles that can damage a fuel injector. A damaged fuel filter can result in erratic performance, poor gas mileage and in some cases, complete engine shutdown. Even the smallest particles can cause considerable wear and tear to an engine. Protecting the fuel system and the engine from harmful particles, helps to prolong the life of your vehicle. Ensure dependable and trouble-free performance with a Bosch Fuel Filter.
Gasoline Fuel Systems
Constantly evolving technologies and state-of-the-art manufacturing over the past 35 years allow Bosch to supply fuel pumps with tight tolerances and compact design, making way for the latest advancement — turbine pump technology. This revolutionary technology replaces older pump designs, providing improved drivability and reduced hot-start problems.
Bosch supplied the industry’s first fuel injection system with a high pressure electric fuel pump in 1967. Since then, Bosch has stood at the forefront of fuel system technology, providing fuel pumps to virtually all vehicle manufacturers. Compared to conventional fuel pumps, Bosch Pumps deliver 30% higher efficiency and the precise fuel supply required for a partial or full load – saving fuel and reducing CO2 emissions.
The high pressure pump is responsible for compressing the fuel supplied by the electric fuel pump to the pressure required for high pressure injection up to 20 MPa (200 bar).
Bosch Port Fuel Injectors (PFI) have a robust design and are capable of using Ethanol fuel (E100). All Bosch fuel injectors released to the aftermarket are OE fit, form and function, and are produced to OE specifications. The Bosch fuel injector has a return rate of 1 part per million (PPM), making Bosch the industry benchmark.
Bosch Gasoline Direct Injection (GDI) provides the basis for a cleaner and more economical engine generation. At the same time, it contributes to the current engine downsizing trend.
