I purchased my 2015 Evo X GSR just 2 weeks ago. I decided to change the cabin filter because whe I used the AC, I could smell something funny. like gas, oil, or anything else, but nothing pleasant. When I opened up the location to change the filter, I was shocked with the condition of the current filter, and all the crap in there. See these pictures for more detaills.

 

You're going to want to pull the blower motor too. I bought an 02 s2000 a few years ago and the cabin filter was so full it pushed down into the blower motor dead baby mice and everything. For the cost of a filter, I now make it a yearly maintenance item.
After you get everything cleaned up with the cabin filter out (blower motor pulled, cleaned and reinstalled, you'll want to spray some lysol disinfectant into the area where the fresh air comes in from. On my honda it's under the wiper garnish on the outside of the car. Not sure where it is on an Evo X but I'm sure it won't be hard to find. Spray a light mist in on each hvac setting one at a time and let the system run for a few minutes to dry everything you sprayed in before moving to the next setting. Should improve smell drastically.

 

Thank. I had pulled the blower out and washed it with good water. I did not sprayed Lysol, but thanks to your adviced, I just went now to my car, and did that. I then turned on the air conditioner and I can feel the difference. Now, the car feels so fresh and clean.

 

It’s great to hear that the Lysol trick worked for you! Keeping the cabin filter and blower motor clean is crucial for maintaining good air quality inside your car, especially when dealing with odors like you mentioned.
