well I just installed a Banks intake system on my 08 2500 and I must say it was a pleasure. The instructions were clear and precise and the many pictures were of great help. It was so easy...... and everything fit !!!!!
My last truck I installed an AFE intake system, it took a half day, nothing fit right and it's a good thing I have a well equipped shop because I need to do alot of manufacturing of brackets ( yes it was the correct # )
has anyone had good or bad experience with the other brands ?

 

I purchased an AFE MEGA CANNON II about a year go on my 07. Excellent! Very easy to install and flows great. Didn't notice any difference in EGT's.
