Correct me if I'm wrong please.

The contents of a Stage I for a 2005 EFI Fatboy consist of:

higher flowing air cleaner, higher flowing exhaust, a re-map if staying with the Harley ECM.

The real question is: are different spark plugs part of the system?

Thanks,

Wolf

 

No.

 

Here's something that will explain a stage 1 , plugs are not included in a stage 1

The Stage 1, according to the HD Catalog, is an air cleaner and re-map for FI engines. It is advertised as street legal when used with stock pipes. Thus, pipes are not part of the equation, but should be.

Bill

 

Couldn't have said it better myself.

Thanks folks. No plugs. Just curious because as in another post I did on this forum, my dealer (know the owner/Master HD mechanic well), dinked with new plugs and the EFI ECM after I had already done the Stage I and gawd amighty it runs with MUCH more power now. He just told me he did a little tuning...well, it's an awesome running Fatboy now. Never ridden a stock displacement HD with stock heads and cam that ran so strong as what's in the garage now. I'm happy.
