Bike is a 04 roadking fuel injected stock. Should I just use the se kit with new filter and backing plate. Which ones come with the k&n filter. Thx

 

Are you asking if you should just change the air cleaner and nothing else, or are you saying you're doing some mods to include changing the air cleaner anyway so should you just use the SE kit? The SE kit does not come with a K&N filter. It has a washable but non-oiled filter. AN Big Sucker comes with an Airaid filter which is identical to the K&N and is slightly cheaper than the SE.
