    I heard a thousand different reasons why not to, and why to turn over the air cleaner cover on my 350. Anyone know what gains/damage can occur from flipping it and does an after market really do much accept make it sound better with a stock intake and exhaust?
    I tried it on my latest trip back from Seattle! I flipped it while still running at a rest stop...drove off....then threw a code...then fixed itself! Stopped again...flipped it back...drove...threw a code again and corrected itself!

    HMMMM.....

    Oh wow...so that's worth it right there!
    What about feeding it that warm air from the engine compartment? Isn't that bad for it?
    Does your filter get dirty much quicker?


    It does sound damn good too!

    I just flipped mine last week and I like it. Better MPG and I think its better than trying to suck in air from the fender not enough flow IMO.

    With all the mods to my engine I have to flip my lid to allow more air. It only sucks in hot air when in traffic. While going down the heat goes down under the truck.

    I don't know if it's flipping the lid, or using more throttle causee it sounds cooler but I lost MPG that's for sure.

    It lets air flow more freely into the engine.
    Yes your filter will get dirty faster. But if you have a reusable filter you can clean off, you won't have to keep buying them.

    How do I go about doing this? I don't see any way to flip the lid over.

    Re: What does flipping the air cleaner cover REALLY do?

    Isn't there a wingnut or 2 on the air filter cover?
    If so...remove the nuts, flip the filter cover lid over and re install wingnuts! Should be pretty straight forward man!

    you take the wingnut off the top...take off the lid...flip it upside down...put it back on the stud...screw the wingnut back on...then...your...lid...is flipped.

    If you want to do this to your truck....assuming it is the 96 you have in the sig. You dont flip anything....you just take the top half of your air box off and expose the filter.

    Sorry I've never heard of this before. I thought it was a little more complicated. Why don't people just buy an open element air filter from advance auto for $15-$20?

    Re: What does flipping the air cleaner cover REALLY do?

    Oh... that makes sense. Is this okay to do? Will it harm my engine in any way, or shorten the life of my K&N? I get 11 mpg, so I'm looking for anything to up that.
