Is a K&N Air Filter worth the money in a 5.3?

My 2006 is a daily driver and I'm looking to get a K&N Air filter for just a slight improvement in throttle response just for the heck of it. I've heard that the full CAI system is not worth the money by itself because you'll notice very very little difference. That's why I thought about going for the filter, it's much cheaper, easier to install, and I can pick it up at my local Advance Auto. What do you guys think? Is the filter worth the 50 or 60 bucks?

By the way, I have an exhaust system installed but it's not Flowmasters like my sig says. The mechanic told my dad that it was just like Flowmasters but much cheaper and he's put it on countless newer trucks. It sounds great, but I have no idea what it is because I got it put on as a gift. Don't know if that helps answer my question or not!

I hate to pile onto these kinds of boastful discussions but I'd look at your Long and Short Term Fuel Trims after doing a cold air intake mod. Some of these mods cause a lot of chaotic air to reach the MAF sensor which confuses it.

It's sometimes like rearranging the deck chairs on Titanic. Why bother.

Lol.

Also street speed 717 is a local guy to me. Everyone hate him. He does nothing but make click bait videos, that run was altered for YouTube hits and for him to get money from cai

Again.. I have that exact same intake, and truck..

If you bought a cai that cheap my bet is it's the open box one. Which WILL be less efficient than your stock box.

But before you turn this into another circus. I'm out. Enjoy your 5+5=15 mods.

I hope this gets in before it becomes the top of the Locked heap!

Any way,, 15HP is 15HP. I like that. If you can feel the improvement and you get improved performance, then you got a good one.
No matter who makes it, If it works and you feel it and like it, then Money well spent.
I feel I spent Way too much for what I got. And O chalked it up to a learning lesson. So well at least I got something.
I did not feel HP gains and saw a mpg loss. So for Me,, Not a believer.

But,, being I didn't watch the dyno video,, what rpm did it add HP? Was it in the power band?
I guess I didn't feel it was because I try not to run it at peak RPM all the time,, even when towing, the only time I got it wound tight is hills and freeway entrance's,, Now the hills,, It all slows down enough so that 15HP will not force my head back.
On the freeway,, well the noise from the CAI was so annoying, I wouldn't be trying to feel an extra 15HP.
Oh I also cranked it up when passing,, but still, it all seemed like slow motion so that 15HP was a mute point.

My days of making noise from the back and getting it from the front also are way long gone,, that all just pertains to before and after dinner now!

At my age,, what would be a good HP gain so that I could feel it and what do I need to get it there? I have run E85 and supposedly I get HP gains,, but the fuel gauge dropping so fast mutes that out..

If you are happy with the K&n then thats great, I was excited when I installed all of mine,, but the luster wore off fast.

With all the searching I've done I'm satisfied that spending the money on a k+n filter is worth the money. If I had 300 bucks I would spend it. I'm too poor to pay the money. But the k+n also should last a million miles so. My last one lasted 11 years of service in 2 vehicles.

There is no debate. You're acting like a child; as if were all supposed to go search the internet to backup your argument when everyone disagrees with you. You're even trying to change what vehicle this was about.
Personally, I don't believe you have bought and installed 15 of these, and based off your response you sound like a teenager who doesn't know jack****.

Lol yeah. I have the intake that they use in those "15hp" gain videos.

I didn't experience any gains.

You realize most of us on here are speaking from real world experience messing around with various configurations and parts.

I just watched a 2019 chevy 5.3. Stock it made 296hp on the first pass and 330tq at the wheels. the chassis dyno was an independent shop. I'd post a link but I wont. Its out there if people want to see. I seen the video. The cold air kit produced 15hp. I underestimated by 10. The truck on the dyno was stock. The k+n website claimes 15hp. Guess they know what their talking about.
Post the link. This just sounds like your talking out of your ass without it. Are we having an adult conversation with facts and details, or do you want to say "I could just prove it, but I won't".

P.S. Nobody said COLD AIR INTAKES don't work.... You had a hissy fit about K&N brand specifically.

OP was also working with a 2006. Cherry picking a 2019 to try to prove a point doesn't help you.

A stock paper filter isnt as passive as a k+n. The only way to take in more air is to exhaust more air. It's not one or the other it's both. Has it ever occurred to anyone here that intake and exaust are components that work together. You get 5hp from a filter upgrade. You get 5hp from a muffler. But when you do them both you get 15hp. Where did the extra 5hp come from? Because they both work together.
Well I think I know exactly where that extra 5hp comes from. After Purchasing a complete cold air kit with air box, tube and wet filter I was sure I was going to see remarkable fuel savings and feel a HP gain when towing my trailer.
Truth be told, my fuel mileage did not change one bit. But in my mind, way in the back of my mind I could feel that extra 5hp Every time I pressed down on that long skinny pedal I could hear the whoosh of air growling into the engine.
Each time I pulled my trailer that complete CAI system that I spent a great deal of money on just growled along letting me know it was still there making POWER!
That vision of the money going over the counter and that big box I got, the afternoon I spent wiping down my engine compartment and shining up the new cold air system and how proud I was to see it when I opened the hood kept playing over and over way back in far depths of my mind telling me it was a wise investment and was surely adding pulling power,,,I could actually feel it in my seat!! Oh boy it was glorious!

Then after a years worth of pulling that trailer and watching my fuel figures it started to dawn on me It did Not help my MPG's at all!
And it started getting on my nerves that constant growl from pushing that skinny pedal down cause the more I pushed it, the louder that noise got and the voice in my head was telling me thats the sound of allot of fuel and air being sucked thru that big air pump under the hood!
The louder it got the more I realized I had NOT gained any extra Horse Power and I was just kidding my self and my wallet!
So I am of the opinion that these are for Race purposes only! And only for looks on the street.
I think the person who supposedly bought 15 of these things, and noticed 5hp increase across the board..

That's good reading right there. For years everything I bought got a K&N stuck in it. I'd pull em and wash em as needed, throwing a paper spare in for the day+ it took to properly dry and absorb the oil after I applied it.
The older I get, to hell with washing and oiling filters. Wix, Fram, GM, other asst. manufacturers all make filters that drop right in place in a matter of minutes.
I am however thinking of a modular intake tube to kinda clean up the airflow and under the hood. The dyno curve showed hardly any gains, but the curve changed to lower rpm. Getting old and all, lower rpm is where my truck will stay.
