I almost went with the Roush because of the great looks and high quality, but in the end I went with the K&N because I have owned them in the past and they always worked as promised. I have it on my 2014 5.0 and I noticed the power difference right away. K&N also encloses a written HP guaranty along with their dyno chart. For the 5.0 peak gain is 12Hp, but the torque and HP show gains across the RPM range. The sound is great as well. Opening up the exhaust some does wonders for these motors and goes hand in hand with the cold air intake. Hope this helps.
Howdy!
Nice first post .
Unfortunately you were mislead by K&N's Armani-suit-festooned Marketing Department; those 'gains' are grossly inflated.
That 'guarantee' is not worth the paper it was written on. Do you think they'd reimburse you fer the dyno time to confirm those numbers on your truck? Of course not. They rely on the boiler-plate that 'YMMV'. And - they conveniently neglect to mention that their intake risks leaning out yer motor due to MAF TF skew (why do you think custom tuning shops write tunes fer specific intakes?).
I'd read the fine print. Or better yet - return the POS fer a refund as it's a spectacular waste of money.
The majority of the people that claim they "feel a noticeable increase in power" are victims of the placebo effect created by their seat-of-the-pants dyno and the need to justify why they spent so much money on a "blingy" item. If any of these companies would like to put this entire debate to rest, they can take my bone stock 5.0 engine, dyno it for a baseline, slap an intake on it, and dyno it again. If there's any measureable gains greater than 5 HP, I'll buy it. Until then, it's a bling mod for these trucks IMO

+1. I put an in the fender cold air intake on my 04 cobra, and noticed nothing, aside from the supercharger sucking air. I'm sure it helped bc the intake was actually no longer under the hood, and was actually getting a cooler ambient air temp, but even then it was minimal.
I had a K&N on mine bought it from someone really cheap only reason I did. Wanted to see if it "really" did anything. The little HP I gained weren't noticeable to me and the only thing it did was give the truck this annoying roar I couldn't get used to do I removed it. After that I just replaced my stock air filter with a cleanable one and never looked back. Like the previous post states only way someone would be able to see real results from one would having it function properly with the hood scoop and all. Most people think they feel the power difference it's just the noise that it makes sounds like there getting. All in their heads.

. First off, k&n did dyno a bone stock 5.0 and then one with their kit. The sheets are posted on their site. It shows a 12 hp. gain. You can believe it or not, that's up to you. 2nd, I have been modifying these modular engines for over 20 years and I have been on the dyno with various mustangs over 50 times. The Modular engines. 5.4, 4.6 and the new coyote 5.0 respond well to four things in particular. An upgraded air intake, a free flowing exhaust , a tune, and boost. The exhaust or air intake offer minimal results if done alone, combine them and the results are there. Look up past articles in muscle mustang and fast fords. They have run tests on each of these engines, they always do a baseline, then one mod, re test add another , re test and so on. Will I dyno my f 150? No, I save that for my GT 500. Do I need to justify "bling". Lol, hell no. If I don't like how a part performs, I take it off. For my truck, the filter and exhaust made the truck come alive. Alive like my Shelby? No, but that is not the goal or expectation. So for what it is worth, I see value in adding a good cold air intake early on as a building block to future mods.
You already have the 'best' CAI - yer Stock one. it flows far more than yer Stock engine can use (and keeps the IAT's in check).
Aftermarket fer appearance ('bling') and some noise. There is NO perf advantage.
BTW - K&N is crap. Marketing BS.
You have a MAF - beware yer MAF transfer function accuracy if yer chosen aftermarket CAI relocates the MAF.
This particular vampire was staked - long ago. Only fellers who are card-carrying members of the Flat Earth Society buy CAI's fer perf these days.
Flame on. lol

I put a Roush intake on mine. It made a little more noise but that's about it. I also didn't like how water dripped on the filter everytime I opened the hood when washing. I think it may have actually HURT MPG too. I ended up reinstalling the stock airbox but left the smoother Roush tube in place.
Not looking to argue for or against. Someone above posted some of our results. I will just say our top seller is the S&B 5.0L intake. As far as quality of the kit and price point, this kit offers both. We do have this intake on our 5.0L project truck.

If the truck that K&N actually used was truly "bone stock" I'd find that hard to believe. I've been modifying and dyno-ing cars myself for more than a decade, and I've never seen an intake make 10+ hp out of the box. Don't get me wrong, it's a great building block with a tune and a free-flowing exhaust, but honestly all mods are negligible without a tune to take advantage of them. To say "I notice a real HP increase" from a simple intake on a naturally aspirated vehicle would be an outright lie that the intake companies greatly appreciate

I'm not as experienced in modified ford modular motors like you, but I have modified quite a few cars and typically I've noticed that adding an intake at stock power levels makes no difference, and sometimes the powerband suffers negatively in the low end. However, once you start modifying and take a 260 hp motor upwards of 400+ hp, that's when the bottleneck becomes apparent and the need to modify the intake becomes apparent.
For stock motors, the stock intakes have the money and engineering behind them to be more than efficient. Just my 2 cents.
...and I'm with LoadSmasher on this one, I don't believe their claims of 12hp....unless they just needed a new filter in general.
