Engine Air Filter Replacement
 

I have a 2004 XC70 with 135K miles. I am noticing loss of accelaration. I replaced the air filter. Come to find out it is the cabin filter (BTW, I noticed it was the original one- mfg date 2003 made in France). I cannot find the location of the engine air filter or how to replace it.
I called the dealership and they gave me part number 9454647. That looks the same as the cabin filter.
Any guidance?

BTW, I also noticed that the batter on the 2004 is still the original one. Go Volvo!

Pretty hard to mistake the two. The cabin filter is under the dash, the engine air filter is in the airbox, right behind the left headlight.

Thanks ES6T. I will look it up. Any tricks/cautions to replacing it?

No, it's very simple.

Here is how you do it:
