Slow accelaretion mitsubishi adventure - Montero Sport Mitsubishi Cars & Trucks

I you have a owners manual you might look in it to see if it tells if you have a cabin air filter.
I have changed them in several vehicles in my time and the one's I changed was behind the right hand glove box or right side under dash/glove box area. I think I would take a look in that area. I put a couple link which may help but are not for Adventure.
