ms3300, I wouldn't change to a different breather assembly without addressing the VE (and spark timing) table changes in the ECM. The XIED is too much fuel for the O2 sensor in its own right and none of the IEDs do anything for the fueling change needs brought about by altering the intake (or changing the type of exhaust plumbing). The *IEDs are merely external means of adjusting the ECM's O2 sensor bias/target voltage.

If you're running your bike totally stock or if you've got the right parts to match a download and are using them/it, then the standard IEDs are what you want. Running or wanting anything different, none of the IEDs are what you need. And in any event, it seems the engineers/programmers have found a way to thwart this method of breaking the law for the '09s.

The way our ECM determines the amount of air flowing through the engine requires that the discreet values in its VE tables are correct. The *IEDs do not address that; they are merely means of externally adjusting the ECM's closed-loop bias tables. In order to work correctly they need the ECM to be properly programmed for the parts. Any other combination or use of them is just plain nuts. Maybe if it was on one of the $1500 Chinese scooters running the streets anymore, but not a new H-D road bike.

If you have a means (there are several) of adjusting the ECM's VE tables to appropriate values then you also have (in every case?) a means of adjusting the closed-loop bias tables internally, so you don't need any *IEDs.

Again, regardless any hype or whatever anyone else says, the IEDs are only appropriate, in and of themselves, on either a completely stock bike (possibly okay with moderate slip-on mufflers only) or on a bike which has a factory "stage 1" download with the appropriate parts. In both those cases the ECM is properly programmed and the IEDs do their job. Any other situation and they'll still do something, but it certainly won't be right in and of itself.

 

The filter that comes with it is a dry filter, you don't have to oil it like you do with a K&N. This filter assembly passes more air than the original unit. It is also not baffled for noise suppression like the original. I was surprised how much noisier it is than the original. In conjunction with a download it really adds some poop to the motor from about 2500 rpm and up. Below that I didn't really notice much improvement probably since airflow demand at that low of an rpm is sufficient with the stocker. It's a cheap and effective bump

the se kit used to come with a k&n filter. then hd decided to start selling it with a paper filter. a lot of folks have found pinholes in the filter after a period of time and replaced it with a k&n. just keep your eye on it, and replace when needed and you'll be good to go.

 

This is why our kit uses a cleanable cotton/gauze filter element with a lifetime warranty and we even include a free K&N cleaning kit. It also features genuine Screamin Eagle components including the backing plate and oem hardware and costs less money than the Harley SE kit as well.

 

That is the reason I switched mine to a K&N element, two years ago. I ordered it through AutoZone, for $42. The HD, SE, blue and black, air filter elements, are junk. Pieces of the element could be sucked into the engine, as it deteriorates.

another reason to buy from jamie

 

My kit came with a white filter and when compared to the k&n it looks far superior. Something new?
