Decided to change out my cai system that uses the OEM MAF section. It's only 2.35" ID which matched the throttle body. Now that my TB is 2.48", I need to have the piping bigger. From the way I understand it, your intake should taper down in size and not up. Tapering down would increase air flow like air going through a compressor on a turbo. I'm going with 2.75" OD pipe or about 2.63" ID. That should have the system bigger than the TB and really help. I bought new MAF housings and they showed up today. Only $40 on ebay. I'm still waiting on the pipe. I'll post pics soon.
