No, I don't think you do. It might be beneficial to get a higher-flow airbox assembly but it might not. The question you have to ask yourself is at what throttle position does the stock airbox become an impediment to airflow and how much time do you expect to spend there and above?

That's not my main point, however. I merely want to sternly caution you to not run your bike with any modifications before you get the PC installed and put into service, as tempting as it might be. Then, do not re-enable your O2 sensors at any time. If you do, the stock ECU will change a fueling factor it maintains via the O2 sensors and it will rock your world. Trust me on this.

 

I was for a while. PCIII and K&N AC with stock pipes. Can't begin to tell you what a difference it made - in performance and heat.Fuelmoto had a MAP just for this. Best $420 I ever spent.

Later added SE slip-ons and loaded a slightly different map. Performance/heat-wise,didn't notice a lot of difference. Maybe a littlemore oomph. Not a big difference.

Not to change subject but... installing IDS tonight. Will soon be saying "best $225 I ever spent" - I hope.

 

the new filter is no longer a k&n, it is a paper filter that has been known to get holes blown in it after a couple thousand miles. you can 'build' your own screamin eagle kit for less money and still get the k&n lifetime element..... to me, thats the way to go.


you can buy the filter element (hd-0800) at your local autozone for about 45.00

 

Skratch,
Thanks, that sounds good. Is your wife running one of the standard maps from the power commander website, one from Jamie, or a custom? Just curious since I will be looking for a similar map soon.

 

she's running the map from jamie.
