Default Will an S&S air cleaner kit provide noticeble horsepower increase?

I've been looking at some of the S&S Air Cleaner kits, particularly the Stealth.

This is for my 1994 EVO engine, currently all stock. Will the power increase be noticeable with the S&S kit or is it one of these "you might actually just be imagining things" situations?

On your bike, negligible. But between your ears it will be the greatest expenditure of $$'s you've ever made. Plus it will give you the ability to show off and brag about your new air cleaner to all the other guys at your next HOG ride.

Will it make a difference ... yes.
Will it be a big difference ... no.
Why? It doesn't cost enough ... horsepower is measured in terms of cubic dollars ...

That's what I was sort of thinking. I'm also bugged by the fact that they'll only accept an OEM cover from 1999 on.

That's what I'm learning.

It will make a noticeable difference in the weight of your wallet.

Just get a stock air cleaner element or K & N.

Now, a cam might make a diff...

I had a 1995 80" EVO.

The cam I had (for over 100,000 miles,) was a
Crane
"Fire Ball"
316-2B
Comes "on" at 3400rpm.
Loses a little around 1500 to about 2500.

Added about 9hp. (54 to 63!)

Well, I have nothing but an S&S intake and a FUEL MOTO micro tuner. Completely stock, fully catted exhaust. And just that made some nice notable gains in power.

Mine's carbureted so that wouldn't apply.
