They advertise 20% increased HP, which is a very optimistic number if you ask me, considering that is near 40 HP, but from what I have read, people have noticed 10%+, which is still around 20 HP. I'm not sure why people assume that we want more HP for "1/4 mile times"; i just want more HP to turn my 35s, to reduce the number of downshifts, and to increase fuel efficiency.
20%? You won't get 20% without spending at least 3 grand unless you go nitrous.

How do you "notice" 10%. Butt dynos are not that accurate and dyno sheets are notoriously manipulated.

I built my own. Would i buy one... Nah. And yeah 10% is a big gain, doubtful you would see the extra 20hp. Not trying to stray here but the whole percentage thing is really kind of a misleading thing, for instance... My boss just had a 468 big block chevy built for the shop truck ( fully custom hand fabbed 68 chev) all roller cam, AFR heads, scat crank yada yada. Engine builder says easy 625hp. We do several dyno pulls with it with a dual plane intake and a vacuum secondary( choke wheez) carb. Best number... 540hp. Nothing to sneeze at grant you. My input was go for the single plane intake and a mechanical secondary. Dyno guy says, no way those are a pita and will only net 10-20%. So i split the difference. Were all smart here, do the math. Sorry for the rant. Do what u want man. Its yer$$$ and yer jeep. Even if you only see 3hp and 1mpg it will pay for itself in a a few tanks of fuel.

Since there seems to be so many doubters of the all mighty and always accurate butt dyno, I'll help you get the results you need to prove you have serious gains in HP, MPG and torque

Butt Dyno

Buy a winch. It'd look cooler & you get better power gains.

Down side:
Technically, they should let more dust in, especially when not using a pre-filter.

My experience:
I bought k&n for my mustang and jeep, threw them both out after 2 weeks of dealing with MAF sensor problems. I didn't even oil them, since they come pre-oiled. I bought the AEM dry filter and have run it for 12 years now (140k miles), no problems, and no dust in the intake.

Again, no performance gains, but I am not seeing any drawbacks either. But there will be MANY who disagree with me.

You forgot to factor in the placebo effect.
