K & N question
I have recently acquired a completely stock 2006 FLHRSI. It will soon need a new air filter and I was thinking I would install the K & N HD 1499 for twin cam 88's. I won't need to change anything else on the bike because of this, will I? It's just a replacement, albeit higher flowing, filter element. Thanks.

I would say probably no additional changes required. The difference in flow will be very marginal. I think the airbox is more restrictive than the filter. Now would be a good time to consider a stage 1 upgrade though...

There is a chance that it could lean it out too much. A stage I is probably a good idea if you do. With a stock exhaust, the performance gains will be minimal at best since you aren't increasing the overall flow of the engine with the restrictive exhaust (if more air comes in, it needs a way out). I used to use K&N's on my cars, but have gone back to paper. The reason the oiled element filters flow better is that they allow more through. To me that means more dirt flows into the engine when they are clean. They even claim they filter better as they get dirty. I'd personally stick with an OEM filter. They may cost a bit more to replace over the years, but you'd also be saving a lot more money by not having to do any tuning work. That's just me though.

I have a K&N on my Ultra with IED's and no problem, I
put the IED's on to richen it up for cooling the exhaust
down and they helped for that and more. I have been
a fan of K&N's for quite a while.

The op's bike doesn't have that option. Either just do the filter and rock on, or go all out and do a stage 1 with a tuning device.

There should be no problem with installing the K&N except for the fact that you have to clean and re-oil once in a while. I think you will find that the OEM filter will filter the air better.

What are we talking about and why wouldn't it work on my bike? Not being a smartass but I just got back into a bike after a 20 year hiatus and I'm not really up to speed on all the new terminology and gadgets. All I know is it's a 2006 Road King Custom FLHRSI (injected). If there's something out there to make it run cooler I'm all in.

Keep them clean and properly oiled and it isn't an issue for most. Have you ever heard of anyone loosing an engine due to one? Neither have I.
I have one in my ZRX, and a Ness Big Sucker on the HD, which is basically a K&N knock off, I run the one on the HD as an open element, and when I just had the cam case open I saw no signs of wear due to contamination.
Now will it lean the bike out... ya just a little, if you are not running some sort of a tuner time to get one, there isn't a HD ( and a few others) out there that does not benefit from a tuner of some sort ( assuming EFI) because the factory settings are to please the EPA, not to make the bike run right
I have seen car engines destroyed from running no air cleaner though....
