Are OEM Mazda Fuel Filters Better Than Aftermarket?

If you're shopping for a replacement Mazda fuel filter, you may have an important question:

Are OEM Mazda fuel filters better than aftermarket?

We'll let this comparison guide answer your question. We'll go over the 2 important factors that go into a fuel filter. This will help us determine which type of fuel filter offers more value.

1. Fitment

The fuel filter is one of the most important parts of your Mazda's fuel system. All the fuel in your car runs through the filter before making it to the engine. It's so the filter can clean all the impurities out of the fuel before sending it to the engine.

To maximize a fuel filter's performance, it needs to come with the right dimensions. It's so:

  • The fuel filter is big enough to handle the amount of fuel that passes through
  • The fuel filter is easy to install
  • The fuel filter doesn't leak

Mazda OEM fuel filters are exactly like the fuel filter that came on your car. That guarantees perfect fitment, every time.

Aftermarket fuel filters are rarely designed to OE specs. Some aftermarket parts can perform better than OEM parts, but this isn't true for fuel filters. An aftermarket fuel filter without the right dimensions can cause problems for your engine. This is even true for fuel filters with dimensions that are slightly off.

2. Material Quality

Filter quality

Material quality is important in fuel filters. You want your fuel filter to perform reliably as long as possible. The fuel filter comes with several different components, including:

  • The housing
  • The filter material
  • A built-in regulator (in some filters)

It's important for all these components to be built with high quality materials. Let's say the fuel filter housing is made from low grade materials. The housing will fail sooner or later. It may spring a leak, crack, or it may rust out fast.

The filter material is arguably the most important component of a fuel filter. It traps impurities in the fuel. If you want a fuel filter that lasts, get one with high quality filter material. It needs to:

  • Be able to withstand up to 60 psi of pressure at all times
  • Have the right amount of correctly-sized pores to let fuel - but not impurities - through
  • Have deep and tightly spaced pleats to ensure enough filtering capacity for the life of the filter

Mazda spent a lot of time engineering, developing, and testing its fuel filters. The result? OEM fuel filters with high quality materials that will last a long time.

You can't say the same about most aftermarket fuel filters. Aftermarket manufacturers are notorious for saving a few bucks by using low-grade materials. You could get away with using some cheap aftermarket parts that don't affect your engine's performance (like wheels). But as far as fuel filters go, OEM is always the safer option.

How To Find An OEM Fuel Filter At Aftermarket Pricing

At this point, you may be asking, "if aftermarket fuel filters aren't great, then why are people buying them?" Our best guess? Cost. Aftermarket fuel filters normally cost a lot less than OEM fuel filters. OEM fuel filters can be expensive because:

  • OEM fuel filters come with high quality materials and the right dimensions
  • Dealerships mark up their prices, usually by 30%
