I'm trying to figure out how to do a custom cold air intake, but I don't know what to do with all the sensors and stuff. Especially the mass airflow sensor. If you could tell me what you have done and/or post pictures, I would appreciate it. Thanks!
 
I started by doing a resonator delete and adding a K&N filter. I then took out the air straighteners found in the upper aft part of the air box ( less restriction ). While you're in here its a good time to clean the MAF sensor considering you have an 05 its probably dirty as hell, and hey, why not the throttle body while you're at it...

I then cut the previously removed resonator about 4 inches down from where it leads in to the bottom of the air box. This dips down perfectly to the cool air section under the car. I drilled holes in the cut section of resi and where it meets the air box and put a screw through there to whole the two pieces together.

works beautifully. mad flow yo. HA!
