It appears the stock intake draws air from the fenderwell. Has anyone checked to see if there is a network of plastic tubes in the fender that might restrict airflow? If so, can these be removed to flow more air? Also, has anyone considered modifying the stock airbox to flow more air? The "deckplate" mod is common on the Toyota forums and you basically create a hole in the airbox (below the filter) in order to draw more air. The construction allows you to plug the hole for off road or high water situations. There is a guy on the Toyota forums that did dyno runs comparing the factory airbox mods to open cone intakes and CIAs and found that modifying the factory setup produced more power. I'm going to check this out this weekend, but just curious if anyone has looked at this option.
Oh, if anyone has installed a CAI and is willing to part with their stock airbox, shoot me a PM. I would be interested in having a spare so I can check some different things out.
Thanks!
