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.

Premium engine performance requires a premium oil filter. Bosch Premium Oil Filters protect your engine by keeping harmful particles and dirt out, preventing premature wear and engine failure. Premium oil filters not only fit the same way as original OE filters, they utilize an exclusive blend of natural and synthetic materials in the media for superior oil filtration and increased engine protection.

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.
