What is the clean air mod on a F4I?

For the minimal sotp that you "feel" you gain..you are probably in reality not gaining anything...just messing with how an engine is built to perform

It throws unburnt air/fuel back into to the intake system. Like I said it's Dyno proven mod so why would it be bad? Your hooking vent to vacuum pretty much in theory since the pair valve is just a tee now. As for the picture I just flipped the pair vavle around so all 3 lines can be hooked up and took the internal spring and washer out of the valve to act just like a tee(free instead of buying a tee) Plus you keep your pair valve plugging into your system.

I'm just as lost. I'm really interested in cheap mods though considering I just dropped $352 on tires, 59 on a cam chain tensioner lifter, 10.99 on grips, 9.99 on bar ends, 29 on a new battery, 6 on a homemade fender eliminator, 44 on a new chain, 16 dollars on air filter cleaner and oil and another 9.99 on chain wax.... all that being said I still havent told you about my mounting and balenceing fees for hooking up the new tires which is 27.90 a tire.... I'll just feel blessed if this adds a couple horses along with the smooth air duct mod that eliminates both upper and lower resonators

This is the thread that convinced me to do the clean air mod a few years back.
It actually produces MORE vaccum in the crankcase resulting in more power. Dyno proven! I've been searching all morning and cant find the dyno sheet i saw years ago.
