Poor Quality Filters can be very expensive

Cheap oil filters have a poor flow of oil and can damage the engine at higher revs. Cheap Fuel filters allow debris to flow to the injector nozzles. Its best that you buy original filters or reputable brands to avoid premature engine failure.

Common reasons for Fuel pump failure

Fuel pumps for most cars are designed to be submerged in fuel for cooling. Many drivers tend to drive their cars at empty with just enough fuel to get them to their next destination. This leaves the fuel pump above the fuel level causing it to over heat and fail.
