    I didn't notice a write up on the V6. So i figured I would write one.

    First off what you need:

    10mm Socket wrench
    Flat head Screw Driver
    Phillips head Screw Driver
    (Optional: Electric Drill/Drill bit)

    I don't Have pictures at the moment but i will post them.


    1. First off start by lifting the engine cover by undoing the 10mm bolts holding the cover down. You can pull the cover off and set it out of the way.
    2. The MAF sensor is on top of the airbox. Undo the Sensor.
    3. Once undone, Loosen the air hose by unscrewing the Clamp on the hose.
    4. Undo the clamps on the airbox to open the box to reach the primary filter.
    5. remove the primary filter box and primary filter. Just set them aside.
    6. On the part of the airbox that remains is the secondary filter. There are several options to remove this:

    • Use the flat head screwdriver to pry each of the plastic holders that are built into the airbox. You will have to break the holders to get it out
    • Option 2 is to drill them out (I don't recommend this because the filter box is still in the engine and it is really messy and a pain to get all the plastic shavings out before you start the engine)
    • just cut the filter out and use a little force to pull it out.
    And your done. Just clean out any debris that may remain.(this is important you don't want the plastic in the engine) and put it all back together. Don't forget the MAF sensor.

    I've done it, hoping for even a marginal improvement in MPG. Instead I lost a MPG. I re-installed it. You would think the slightly better airflow with it removed would help performance and MPG, but neither happened. For me anyway. Others have had different results.

    yep.........when i did it on the 06 i had.......i noticed throttle response was a touch better, but the truck idled better, and so that was worth it to me there. no noticeable mileage gain without the sec. filter on the v6, but i have heard its alot different on the 4 banger.

    Makes me curious to try it but I don't know how to measure my MPG I always forget to reset my miles after fillups etc. and can't afford to lose MPG since I drive everyday for work non stop.

    To increase throttle response and Increase in MPG in the 4 cylinders. If its combined with a CAI or alternate filter, i have heard good things. and with a exhaust system too, people say it enhances MPG. Not a huge difference on the V6. But for those who want to do it.

    I think that any time you add more air into the engine you will LOOSE fuel economy. Truth is that the engine's computer adjusts fuel levels to match that of the air levels for a stoich running condition. So if you add more air with out fuel you would run lean and that's not good so the engine would add more fuel to compensate therefore decreasing your fuel economy.

    Someone let me know if I'm wrong here....

    tint, k+n drop in, 2nd filter MIA... Pioneer deh-p400ub head unit...Alpine spr-69c fronts and Alpine 17c rears. Either Alpine or Pioneer amp coming and major sound deadening.
    I did it...response is better down low and when you are speeding up after slowing down for person in front of you turns off road...just seems easier on engine in those instances... as for mpg too early to tell. educated guess is nada either way. seems as if stock was a tad rich and this may lean it out a little...its a wash.
    so...
    for me the only real difference is low end and back up to speed seems to be less taxing on engine.
    does this help anyone? Not really....LOL

    dfpt...did ya get engine build info on harley? LOL

    Does a CAI add more air into the engine? My intake tube takes air from the front fender (i find that strange) but with a CAI it takes it from the air within the hood. therefore adding more air. But CAI increases fuel economy. is my thinking logical or am I wrong in assuming how the CAI actually works?
    If i am right then shouldnt removal of the filter increase fuel economy too?

    The idea with a most cold air intakes is that it reduces the pressure and allows air to flow more freely into the motor, also, cold air is more dense so you will get more air = more oxygen, in the same volume of space compared to if the air was warm. Thus improving power and usually gas mileage at the same time.
