Thanks for the info. As you can tell I don't know much about either.

I was after just the CAI. I like to make one change at a time. Although in this case I am throwing the IPD plenum in there at the same time.

(The tune and headers would come later if they are significantly beneficial.)

How did you find the CAI to perform? Who sells it? I was not able to find it in the techart catalog. I am using the stock airbox
