Automatic transmission fluid
Match the fluid to the exact transmission, not just the vehicle model. A drain-and-refill amount differs from the total dry capacity.
VerifiedBrake fluid and inspection
Check the reservoir and inspect any low level, warning light or changed pedal feel before driving. Repeated topping-up is not a repair.
VerifiedCabin air filter
Check reduced ventilation airflow and inspect the cabin filter where fitted. Follow the year-specific instructions for access and installation direction.
VerifiedEngine air filter
Inspect the filter housing and replace the element on the applicable schedule, sooner in dusty use when the manual requires it.
VerifiedEngine coolant
Check the reservoir level with the engine cold and investigate repeated coolant loss. Coolant type and replacement procedure matter as much as capacity.
VerifiedFront wiper blades
The Bosch catalog lists the front applications below. Each product contains one blade; buy one for each side. Use the blade manufacturer’s fitting instructions for the original arms.
VerifiedSpark plugs
Use the engine-specific plug type. Check the service schedule and inspect ignition faults before replacing parts.
