They explained it here are some pics.
Here's a little extra. The secondary Air filter
, and its removal. This is how I did it. You don't have to do this or even do it my way if you attempt this you are assuming all responsibility, leaving me not at fault in any way. Now that thats cleared up here we go.
Remove these 2 bolts to give yourself room to work.
I used a screw driver and a hammer to tap the plugs off. Just shaving them and prying a little to get the filter out there should be 6 plugs.
This is what you should have remaining in the truck. Leave the screen as it will catch any large debreah. Make sure you clean the area well before replacing the filter and closing it up.
There is another write up on it but hey I was bored.
