5 Best Fuel Filters for BMW in 2020 (Reviews and Guide)

The performance of your engine relies heavily on the quality of fuel injected into it. Fuel injectors play a major role in making this possible as they act as the “Quality Control” before allowing the fuel to proceed to your engine through the fuel injectors.

Without a doubt, the cleaner the fuel injected to your engine the more efficient it will burn in your engine which enhances great performance from your engine efficiently. We live in a world where a lot of people in the car scene troll BMWs for its unreliability but I tend to differ with this group of people. Any part used in these cars should either be up to OEM standards or exceed these standards for it to enable your car to work reliably throughout the year, and this includes fuel filters. A fuel filter is one of the most important parts in the fuelling system of the car, as you’d rather spend a couple of bucks to buy a good quality fuel filter rather than spending much more on getting your car a new engine every two years or so.

What to consider when buying a fuel filter for your vehicle.

Fuel type

Fuel filters work differently on diesel engines as compared to gasoline engines. How? Well, fuel filters that are used in diesel engines need to come with technology that separates both impurities and water from going through the fuel system to the engine block. In addition to this you will also require a fuel filter that is able to with stand high fuel pressure consistently. On the other hand, if your car runs on gasoline you’ll just require a fuel filter that will efficiently separate dirt particles from the fuel that goes to the engine block.

Fuel flow rate

It is very essential to know the amount of fuel that is needed to be pumped into your engine for it to operate smoothly throughout as it will be a guide on which fuel filter will suit it best. You should not use a fuel filter that is equipped with a filter media that is too restrictive as compared to the recommended size by the manufacturer. This is because if the filter media is too small, it will disrupt the flow rate of fuel into the engine resulting to the engine leaning out on fuel which may cause great damage to the engine components of your car.

Efficiency and durability

Fuel filters come with different micron ratings that influence their efficiency. A fuel filter with low micron rating will filter all the impurities in the fuel that is pumped into your engine more efficiently enabling your engine to run smoothly throughout. However, filters with low micron rating tend to have a shorter service life as compared to fuel filters with a high micron rating.

Dimensions

Have you ever been in a situation whereby you bought a fuel filter from the spare parts store and then found difficulty installing it into your car? Well, fuel filters are not universal parts as they come in different shapes and sizes. You should buy a fuel filter that matches the OEM filter because it will automatically be compatible for use in your car as they will even have the same mounting points.

Type of filter

Vehicles come with different specifications when it comes to fuel filters. There are various types of fuel filters i.e. spin-on and cartridge, which is commonly used in BMW vehicles, among others. You should consider the type of filter you buy so that you don’t face any problems when are installing it into your car.

Conclusion

Most people who swear by the BMW brand have one thing in common, they don’t compromise when it comes to purchasing genuine parts for their cars. All of these fuel filters that we have looked at provide your engine with great protection as they filter all dirt substances in the fuel before it goes through the fuel injectors into the engine cylinders. They are among the best choice of filters for your BMW as they will also enable your engine to run efficiently for a very long time.
