'07 96". If you install an air filter kit like the A Ness big sucker or screaming eagle and make no other changes to the pipes will you gain any power and will you have to do a download? I am just thinking out loud. I am probally going to get rinehart t d and power commander but I was wondering if the filter alone is going to boost power? $140.00 vs about $1700.00 Right now my road glide is all stock, just trying to make the right decisions on mods.

 

the air filter is not as much influence as other modifications. the engine is a pump capable of moving so much air. a more efficient air filter won't move more air than the engine can pull in.

 

Actually, while a more efficient air filter won't move more air than the engine can pull in, a stock filter and air box will flow less than the engine can take.

 

My experience: Put on a Big Sucker on my 01 Road King on a rainy cold crappy day. Didn't get to ride it or anything for a couple days & forgot that I put it on. Then I had to take my bike up to the dealership for an appointment one evening and...
I instantly noticed an increase in power on the side roads and on the freeway. I wasn't expecting it at all - so it came as a very pleasant surprise. I was initially like "wtf? Why is my bike running so great???", then remembered the Big Sucker I had put on.

I've heard & read from several experienced & expert sources that the air flow kit is the quickest & cheapest peformance boost you can do - averaging an extra 4-6hp over the stock air filter setup!
