Signs of a Failing Air Filter

Given its vital role in your vehicle’s operation, a faulty air filter significantly affects your car’s performance. Here are some signs that you may be dealing with a bad air filter:

Decreased Fuel Efficiency

One of the most evident signs of a clogged air filter is a noticeable increase in fuel consumption. If your vehicle isn’t getting the mileage it used to, you might want to check the air filter.

Engine Misfires or Difficulty Starting the Car

If your engine is not getting enough air due to a clogged air filter, it may misfire or have trouble starting. You may also experience stalling or rough idling.

Check Engine Light Comes On

While many issues can trigger the check engine light, one possible cause is a dirty or clogged air filter because it can affect the emission control system.

Reduced Horsepower

If your vehicle lacks the power it once had, it may be due to a restricted air flow from a clogged air filter.

Noises From the Engine

Unusual noises from the engine compartment can indicate that the engine isn’t getting enough air, which could be due to a clogged air filter.

An Air Filter Inspection Guide

To check if your air filter is bad, a simple air filter inspection could be carried out. Here’s a step-by-step guide:

The first step to inspect your air filter is to locate it. You can find it in the air intake housing, which connects to the engine’s throttle body.

Step 2: Remove the Air Filter

Next, open the air intake housing and carefully remove the air filter. Be gentle to prevent any dust or debris from dropping into the engine.

Step 3: Inspect the Air Filter

To check if your air filter is bad, hold it up to a light source. If the light can’t pass through it, the filter needs replacing.

Step 4: Replace if Necessary
