I was wondering if anyone could give me some guidance as far changing my air filter. I have had a new air filter still sitting in its box bumping around the trunk for sometime now. I should be ashamed, I know. But any help would be greatly appreciated. Au

Air intake filter or cabin air filter (dunno if we even have one but thats besides the point )
If you are talking air intake filter...
1. Remove the butterfly clip from the airbox resonator, remove the resonator.
2. Remove butterfly screw and ring from intake tube from the airbox lid.
3. Remove the IAT sensor plug
4. You will see 2 clips on the left side of the airbox, push em towards the box lid and lift up. On the right side you will notice 3 slots with 3 corresponding tabs.
5. If you have to, disconnect the intake tube from the throttle body (dont worry its easy). Notice your MAF screen, see if its laced with carbon deposits. May need a cleaning.
6. Remove paper filter. Clean the botton of your airbox out of sand, leaves and debris.
7. If your daring, gut the airbox lid, you will notice a yellow plastic form inside the lid, call your roomate down to help you pry the circular black tabs off the yellow innards and pull like heck. LOL, you have now gutted your airbox lid...well done!
8. Place filter back in (in your new car get a K&N replacement!) Reattaced the airbox lid. Connect the intake tube to the TB and airbox lid.
9. Reconnect the IAT sensor, reattach the airbox resonator
Yes. Especially since I gutted the airbox. Apparently its a 2 or 3 HP improvement and its supposed to improve mileage.
Anyhow, with the airbox gut + K&N you get the best option for intake mods. Now I just want to cap the resonator, and wrap it in insulation as Aurora40 has in his 2002, once the 80mm TB goes on, but I'm off topic
If you stick with a stock filter, its worth it to remove the innards from the top of the airbox.
I couldn't feel a difference with a K&N vs paper. On some cars, you can hear a bit more intake noise, though. I do believe the K&N flows more, and they have independent studies that show it filters more. I tend to believe that too. It seems like a more quality filter than paper, and ultimately lasts longer with cleanings.
I think the main advantage is that it doesn't drop off in flow as it gets dirty. Paper filters definitely do. So, even if the extra flow at first isn't needed, the fact that it doesn't drop off will be useful.
