The Importance of Regular Filter Replacement

Date: Feb 13, 2024

Mechanic fixing BMW

Driving on Portland streets is a joy when you’re at the helm of a BMW. As such, you want to keep your high-performance luxury vehicle in great shape for as long as you own it. One often-overlooked aspect of vehicle maintenance in Tigard is replacing the engine, cabin, and fuel filters. But all three of these filters are vital to the best driving experience for your BMW.

Read on to learn more about these three filters with our guide from the service department at BMW of Tigard. We’ll cover:

  • What does an engine air filter do?
  • What is a cabin filter in a car?
  • Car fuel filter replacement

A BMW’s Engine Air Filter

You need to replace the engine air filter periodically to make sure your combustion chamber stays as clean as possible.

What Does an Engine Air Filter Do?

The engine air filter is designed to prevent dirt, dust, and contaminants from getting into the engine. You’d be surprised what kinds of problems a fresh air filter can eliminate, which is why changing the air filter is a crucial part of regular vehicle maintenance in Lake Oswego.

If your BMW needs a new engine air filter, it might have these problems:

  • Worsening fuel economy on Tigard streets
  • Sluggish acceleration
  • Black smoke in the exhaust
  • Service Engine light comes on

A fresh engine air filter can improve performance, acceleration, and gas mileage. 

We have completely answered the question, “What does an engine air filter do?” Now, we’ll talk about the engine air filter replacement schedule.

Engine Air Filter Replacement Schedule

We recommend replacing the engine air filter every 12,000 to 40,000 miles. Your BMW’s owner manual has exact figures.

Next, we’ll move on to answer the question, “What is a cabin filter on a car?”

Cabin Air Filter

The cabin air filter improves the air that you breathe on every Portland drive.

What Is a Cabin Filter in a Car?

Behind the dashboard sits a lot of wires, electronic components, and ducts for your vehicle’s HVAC system. In one of those ducts is the cabin air filter.

The cabin air filter can keep dust, pollen, smoke, and other contaminants from entering the cabin, thereby improving the indoor air quality.

Signs you need to replace the air cabin filter include:

  • Weak airflow 
  • More sneezing or allergies due to increased dust and pollen
  • Smelly air combined and lingering odors that won’t go away

Give you and your passengers better breathing on Lake Oswego drives when you replace the cabin air filter regularly!

Cabin Air Filter Replacement Schedule

Again, your BMW owner’s manual has the recommended cabin air filter replacement schedule within the pages of your owner’s manual. Our team recommends a new cabin air filter every 12,000 to 30,000 miles or about every one to two years. If you frequently drive in dusty conditions, consider replacing the cabin air filter and engine air filter more often. 

Car Fuel Filter Replacement Guide

Every gasoline-powered BMW has a fuel filter. It’s attached to the fuel line that transports fuel from the tank to the engine.

What Does a Car Fuel Filter Do?

Your car’s fuel filter keeps bits of debris, rust, dirt, and other contaminants from reaching the engine. You need a fuel filter because gasoline storage tanks that hold fuel before it reaches your gas tank might allow dirt, debris, and dust into the gasoline. 

You might need a new fuel filter if you notice any of these signs:

  • Trouble starting your vehicle
  • Sputtering or stopping unexpectedly
  • Less engine power
  • Poor acceleration
  • Reduced gas mileage

Changing a fuel filter when you first see these signs can prevent bigger problems later, and save you money down the road.

Car Fuel Filter Replacement Schedule

Your BMW’s owner manual has the exact car fuel filter replacement schedule. Otherwise, we recommend replacing your fuel filter every 12,000 to 30,000 miles, or every one to two years.
