2020 GV80 3.5T - DIY Cabin and Engine Air Filter Replacement?

Vehicle: 2020 Genesis GV80 3.5T

Hi everyone, I've got a 2020 Genesis GV80 3.5T with about 45,000 miles. I've noticed that the airflow from the AC isn't as strong as it used to be, and sometimes there's a slight musty smell, especially when the fan is on high. I also feel like the engine might be a little less responsive than before.

I'm thinking it's probably time to change both the cabin air filter and the engine air filter. I haven't done either since I bought the car. Is this something I can easily do myself on the GV80, or are there any tricky parts I should be aware of?

Any specific filter recommendations or tutorial links would be great!

ClearTheCode admin answer:

Your symptoms on the 2020 Genesis GV80 3.5T—reduced AC airflow, musty smell, and potentially decreased engine responsiveness—are classic signs that both your cabin and engine air filters are due for replacement. At 45,000 miles, this is definitely within the recommended service interval for both.

Here's a guide to tackling these DIY maintenance tasks:

  1. Cabin Air Filter Replacement:

    • Symptoms: Reduced airflow, musty odors, increased dust in the cabin.
    • Location: Typically behind the glove box.
    • DIY Difficulty: Easy.
    • Steps:
      1. Empty the glove box.
      2. Open the glove box and unhook any dampeners or stopper tabs on the sides that allow it to swing down further.
      3. Locate the filter housing cover (usually a rectangular plastic cover with clips).
      4. Unclip and remove the cover.
      5. Pull out the old filter, noting the airflow direction arrow.
      6. Insert the new filter, ensuring the airflow arrow points in the correct direction (usually down or towards the rear of the vehicle).
      7. Replace the cover and reattach the glove box components.
    • Filter Type: Use a high-quality cabin air filter, preferably one with activated charcoal for odor reduction.

  2. Engine Air Filter Replacement:

    • Symptoms: Reduced engine performance, decreased fuel economy, potentially a check engine light if severely restricted.
    • Location: Inside the air filter box in the engine bay.
    • DIY Difficulty: Easy to Moderate.
    • Steps:
      1. Locate the air filter box (usually a large black plastic box connected to the engine's intake tube).
      2. Unclip the metal clips or unscrew the fasteners holding the airbox lid in place.
      3. Carefully lift the lid (you may need to disconnect a sensor wire or unclip a hose if attached).
      4. Remove the old rectangular air filter.
      5. Clean any debris from the bottom of the airbox.
      6. Insert the new filter, ensuring it sits flush within the housing.
      7. Reattach the airbox lid, ensuring all clips/fasteners are secured, and any disconnected hoses/wires are reconnected.
    • Filter Type: Use an OEM-equivalent paper filter for optimal filtration and engine protection. Aftermarket performance filters are available but ensure they meet Genesis specifications.

  3. Recommended Intervals:

    • Cabin Air Filter: Every 15,000-20,000 miles or once a year, more frequently if you drive in dusty environments or have allergies.
    • Engine Air Filter: Every 30,000 miles or every 2 years, or more often if driving in very dusty conditions.

  4. When to See a Shop:

    • If replacing the filters doesn't resolve your issues (e.g., persistent musty smell could indicate evaporator coil issues, engine performance issues could be deeper).
    • If you encounter any difficulty or unexpected resistance during the replacement process.
