    Looking for pros and cons for an air intake on a 4.0l with a trd supercharger. Any information would be great, and what intakes people prefer?

    Thanks!!

    Urd TCAI if you are willing to modify the bracket a little to move the air filter forward to prevent it rubbing the s/c intercooler.

    Pulls in way more air than stock, and its ambient temps since its pulling it in from the grille area.

    If you are wanting bolt-on, aFe stage 2 si is also a good choice

    Welcome to TW!

    Unlike a N/A truck where intakes do little other than make noise, on a supercharged truck they help lean out your AFR to generate more power. An AFR gauge is a good idea when modifying supercharged systems. Note that a true cold air intake will be fully enclosed like AFE or Volant drawing air from the fender like stock, or draw air from in front of the engine bay like URD. You want to avoid any open filter in the engine bay hot air intakes.

    What does a fully enclosed do for mpg? Increase, decrease? With a SC.

    You want fully enclosed so you are actually getting cold air, which is denser. Exposed will draw hot air and is a downgrade from stock in performance though it will make more noise.

    The supercharger tunes run rich, they use extra fuel to cool the air/fuel charge to prevent detonation, meaning they are literally putting unburnt fuel out the exhaust. Using a cold air intake on a supercharged setup leans out the mixture a bit to get more air in so you can burn more of the wasted fuel for more power, which in theory would slightly improve mpg when under boost since the extra fuel is being dumped out the exhaust anyway, though actual effects are likely negligible. To do this you need actual cold air from and enclosed intake or the URD intake. However that extra fuel does have a purpose, if you lean out to much you will not be running rich enough to cool the intake charge and experience detonation, which if left unchecked will destroy the motor. Which is why an AFR gauge is a good idea.
