I'm all about the mod, don't misunderstand. But I'm not sure it makes a ton of sense to do what is clearly a PITA mod, just to neck-it-down and let it keep breathing through the OEM MAF Housing.

If you increase the volume on the front end, then neck-it-down at the MAF, you may get some increased velocity over the MAF. But then you dump it back out into a larger-volume space (your larger plenum), you'll find reduced volume AND velocity. And likely some unwanted turbulence as well, right in front of your TB.

just food for thought.
Great point! I was under the assumption the MAF housing matched the 74mm TB/ should be right at 3 inches. Is the stock MAF housing on the air box smaller?
