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!
