I had a BBK CAI unit on my 03 auto gt for awhile, but the car never ran right with it on so I took it off. I have the accufab tb and plenum on order and would like either of the afore mentioned to complement it. I was set to get the K&N FIPK, but then somebody told me about the maf. I was wondering which would be better and if there is a prefered brand. Any advice would be greatly appreciated.
