Searching came up with this though.
"14) remove your rear spoiler.. ( mm&ff did a test and it showed almost a 2 mpg increase on the sn95 body mustangs) "

Also. I'm not sure about under tray from bumper to radiator. Should it slope down to the bottom of the stock air "dam" on radiator or stay flat so that it still hangs down? |
Remove the stock dam/lip/underspoiler thingy... it's just going to present frontal area at this point. If you've installed a partial undertray, you'll be compromising the smoother airflow by leaving it there.

There is a nice round tube protuding from the bottom of our air filter housing. Just turn the housing sideways and route a flexable dryer vent type hose to it. Block off the one going into the fender and you got hot air. |
This is where you need to be careful. I've noticed mention of removing the knock sensor... if you remove the knock sensor, you really need to monitor knock yourself, especially when using a HAI or WAI. The car is tuned to use a CAI from the OEM, so adding hotter air that what it would see even in the summer might cause an issue with knocking, especially if you already had an issue before removing the knock sensor.
BTW - The main reason to bypass the knock sensor is that it doesn't work the way it's supposed to.. on just about any car. The knock sensor picks up inert vibrations in the metal of the engine, and translates it into pinging/detonation, so it tells the computer to draw back the timing. Some engines inherently vibrate at "knock-level" frequencies when operating at high speed, so the knock sensor will tell the ECU to pull timing even if you're not knocking.
You can test this by using high-test (102 octane) fuel, and reinstalling your knock sensor w/ a signal feed. You'll notice on the signal feed that even at 102 octane, you're still pulling timing out. Special ECU tuning can avoid this, but it costs money, and is never worth it for a stock vehicle. Unless you're running custom fuel/spark management, it's just a drain on your pocket that you could have spent on something worthwhile.
