Default Modify stock a/c?

On my 2015 SGS, I have the DK Custom breather, K&N filter, and am adding the Jackpot header pipe and FuelMoto download. Looking at the FuelMoto, Zippers, etc. a/c kits I don't see a significant difference in the a/c housing other than two large oval openings.

So, not being cheap but why can't I just cut similar openings in my stock housing?

I think the FuelMoto numbers show that a stock air box will flow all the air you will ever require with 103 jugs.

I have the k&n element in mine. Fuel moto micro tuner and download. For what its worth, the fuel moto download for my tune with k&n element is the same for a big sucker per fuel moto.

If I hadn't swapped throttle bodies...I'd still be running a stock AC cover with a K&N element, you'd be hard pressed to have that become the 'weakest link'.

Might think about drilling some 1/2 inch holes into the back side of you air box.

I with a lot of others on this forum that think a K&N filter in your Rushmore AC housing
will flow all the air a Stage-I or II can use.

If fuel moto doesnt have to change a map from just a K&N filter to a big sucker I would think that it would be enuf too.

Couple things....

The stock airbox should flow all the air your bike needs. Someone who knows of such things told me there IS a little to be gained by removing the screen if you need more.

Second, the stock housing does a great job of keeping the intake noise in, and there's a lot of it. I sold a Ness Big Sucker with the open back 'cause the intake noise drowned out the exhaust noise.
