Hi everyone, Does anybody make an aftermarket air cleaner for a 07 street bob which does not require any modifications to the fuel injection system. I am looking for something smaller than the stock( football looking )cover. I really don't need any more power so high flow is not an issue. Any suggestions would be appreciated. tmatt

 

Pretty much all aftermarket round ACsare designedto flow more air so you will likely need a remap or download for any change.

 

I am pretty certain there is not...most are marketed as hi-flow filters, requiring a remap, download, different fuel ait mix method to accomodate the increased air to the engine...good luck,letus know if you do find one!

you would have to modify the filter to reduce intake.

I've got an Air Filter question. I've always used K & N air filters in all of my cars, looked at my choices for my new 2007 FXD, decided on the RK- 3909, will wait till the cash flow gets better for the new exhaust. (this is another question down the road, don't want to **** off the neighbors getting too loud, but do want to change the exhaust next)
My question, you're all talking about "remaps", "downloads", and "fuel mixtures". At what point do I need to do these? And does it have to be done by Harley Davidson?

 

Travlin, This is a huge topic, you can do a search and find a sh!tload of info. From what I understand, and what I did, you can change your mufflers for slip-ons and do nothing else. Then you can change to hi-flow A/C you will need a remap=download to your stock ECM for a richer fuel mix(easiest and less expensive, just get the download at HD) this is OK, but not the absolute best option...you can buy SERT, Tmax, PCIII, FuelPak etc. these all change your ECM for more power.
