Just changed my air filter - what's the second filter inside the upper housing? Also, could someone let me know where the cabin air filter is located?

Thanks!!

 

Cabin air filters locate in two large boxes on left and right just in front of the windshield.

- Antti -

 

the second is the charcoal filter which

It is a non-restrictive filter, installed to comply with US emissions laws by controlling evaporative emissions after engine shutdown. Removing it will, intuitively, increase your emissions.

some say they feel more power out of it and better economy

 

Does it need to be replaced in similar intervals as the regular air filter?

Thanks re the cabin filter location - I wondered what those two boxes were!

 

How is it a "nonrestrictive" filter?? Its thicker than the normal air filter... Anyway, I removed mine and saw 1-2 MPG better and what I will say is more power. No Dyno results to prove it but the sound is a bit t hroatier and I do think its a bit more powerful. No codes thrown either.

 

For all intensive purposes since you are a do it yourselfer I would change all of them at the same time that way your timeline matches and you are aware of the date!

 

sorry i realized that after i sent it but thanks for the correction

 

This was the very first Mod I did to my car. Lots of good memories here (See link below).
