OE Replacement Super Stock IRF with Pro-Dry S versus DIY Intake? Other options?

To the Ford Forum Gurus... I have called and emailed AFE to ask them about CFM flow data for their OE Replacement line of filters, but I haven't heard back yet. One of the first things I did to my truck (when new-to-me at 175K miles) was replace the stock early 99 airbox with the upgraded Ford 99 airbox, drilled holes all through the bottom and sides, zoodad mod, and installed an OE Replacement Super Stock IRF with Pro-Dry S. It's the black rubber and blue filter material. non-oiled filter just needs shaken out occassionally. Since then I've done the mods shown below, and now I'm thinking about the air box and filter once again. With the mods I've done I have seen a gain in power, and the engine runs smoother and quieter, no loss in fuel efficiency (but no gain either really).
Questions: Does the OE Replacement Super Stock IRF with Pro-Dry S flow as good as the DIY Intake mod? Will another intake system flow better than what i have now? With my current setup do I stand to gain anything from upgrading the intake and/or filter?
Thanks for your advice!

I have no idea what this "Super Stock IRF" is, and I am usually leary of products that have "Super" in them. How are your EGT's currently? What makes you think you need more airflow? What are your plans for the truck? When it comes to filters you have two criteria, one is filtration and the other is CFM, for someone building a race truck CFM is most important, for someone who want longevity filtration will be key. Nothing filters better than the Ford AIS intake system, it flows all the air my truck needs and will easily handle 375 ponies. If you need more airflow you must go to the open element filters, these are quite a bit louder but you can't have both worlds! The DIY is a favorite among many and it performs well on the UOA reports as does the AFE and S&B. So you see it all depends on where you are going with your truck.
