K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2014-2020 Chevy/GMC/Cadillac Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon, Escalade, 63-3082

I've been a car enthusiast for years, and installing the K&N Cold Air Intake System on my 2014 Chevrolet Silverado was one of the best mods I've done. Right out of the box, the quality is evident – the high-flow air filter and heat shield are built tough, and the installation was straightforward with clear instructions, taking me about an hour in my garage. The real magic happens on the road. Performance-wise, there's a noticeable increase in horsepower and torque; acceleration feels smoother and more responsive, especially when merging onto the highway or towing my boat. It's like the engine breathes easier, delivering that extra punch without any lag. And let's talk fuel mileage – I've seen a solid 2-3 MPG improvement on my daily commutes and longer trips, which adds up quickly at the pump. Paired with the throaty intake sound under throttle, it just makes driving more fun overall. If you're looking to enhance your vehicle's performance and save on gas without breaking the bank, the K&N Cold Air Intake is a no-brainer. Highly recommended for any truck or car owner!

Installation: Easy to install but for the emissions hoses I did upgrade to (2) brass 5/8" barb to 1/4" NPT and added my own (4) worm gear hose clamps (get the size that goes from 0.5" to 1.25"). Really a shame that K&N is too cheap to provide these. On the 6.2L the hose coupler to the throttle body seems too large but the clamps are able to secure it in place. Install instructions are clearly written, have photos, and are easy to follow though they don't really tell you which tool to use where in the process. Function: Amazing so far. Really throaty growl from the intake when you start accelerating. I have a Borla cat-back that this intake complements well. Loud in a good way. Throttle response is noticeably better. I am not expecting massive horsepower gains but the Dyno test K&N did showed about a 14 HP gain. I recommend this if you want to improve air flow into your engine and get a nice mean sound. Worth the money to me. I got the plastic roto-molded version because the Black Hawk is slightly more restrictive material and the metal intake conducts heat vs plastic which insulates.

If you've been considering buying this little upgrade, just do it. You won't regret it. Great quality product from K&N and super easy installation. I installed this on my 2018 Chevrolet Silverado LTZ 5.3 liter in a little over an hour. Highly recommend watching the installation video on YouTube. PROS: Slight improvement in HP and throttle response. Looks and sounds aggressive. CONS: Can't say you will notice an increase in gas mileage because you won't be able to keep your foot off the pedal for the angry "GROWL" sound you will hear from under the hood. Don't listen to the negative comments you read about it not sounding as good with the active fuel management system on newer Silverads. Granted, you don't hear anything when you first accelerate. When you hit around 1500 rpm is when you notice the extra gain in HP and then in comes the beastly "growl" sound. I'm sure if this was paired with an exhaust system, the two would sound absolutely amazing. If you're looking for a budget friendly upgrade with several perks, look no further. My only regret is not buying this sooner.

First off, its K&N. So to me the quality is there, cause I am a K&N supporter. I have used them in the past and like their products. If you have ever installed any cold air kit, it is no harder than any other to install. Has a clean installed look. So the good is it flows more than the stock air box. It would almost have too, just by design. Also has very noticeable sound when into the throttle. Sounds good at wide open throttle.....if you like that sound. The bad news is it has a very noticeable sound...lol. If you tow or are in a hilly, mountain, area where you are into the throttle more regularly, you will be listening to it moan...…. a lot! This is just me, but it drove me crazy towing from tidewater Va. up to the western part of the state. Every long grade just got annoying. I had one on my other truck, but don't remember it being that loud inside the vehicle. So, it is cool to listen to at wide open throttle, but a long never ending moan on a long trip that is surprisingly loud in the cab is just not for me.

So, i just installed this in A Yukon XL, 5.3L. took me an hour and a half and I am NOT a mechanic. A couple of things that hopefully help others. Step 13 shows the connection tubing with the number (that differentiates the 5.3L from the 6.3L toward the front of that rubber connector. Let me tell you, if it is in the front of the connector, good luck ever getting the filter piping to fit into that connector! Put that number toward the back (toward the throttle body) and then the piping will fit into the connector, no problem. This was an 1/2 hour issue for me, a lot of swearing, and multiple glasses of bourbon. I would say in general the directions are easy to follow but should be more specific. For those, like me, that are not as mechanically inclined, “attach with the provided pieces” is not all that helpful- I got everything put together tight and fine but was left over with two washers and two lock washers. I am sure that some of the parts I screwed in are supposed to have those, but I don’t know which ones so I am just telling myself they sent extra parts to make myself feel better. Again, anyone mechanically inclined probably knows where those are supposed to go...but I didn’t. Took it out for a test drive and I will say, great engine sound and noticeable low end torque increase. As for gas mileage, too really to tell. I know for me personally, it’s gonna hurt my mileage because that sweet sound under heavy acceleration is delightful. If you have better impulse control I would be willing to bet it will increase gas mileage.

The only thing preventing me from giving this product a 5 star rating is the plastic 5/8” barb fittings they include in this kit, very disappointing. As pointed out by others, these flimsy plastic fittings are easy to break and I myself broke one installing them. I had to go on a wild goose chase finding something to get me by while the 5/8” 1/4” NPT Steel barb fitting I ordered were on their way, I made it work with a fitting i found at the hardware store for now. Other than that this kit is incredible, everything fit perfectly and was well made. Even with a stock exhaust on my 2017 5.3 this thing sounds incredible, I couldn’t be happier. I’ve also notice a considerable increase in fuel economy, though with the way it sounds it will probably be worse than before ;) lol. In terms of performance I was slightly underwhelmed, my truck has already been tuned and this filter didn’t seem to add any additional power to what was already there. All in all, i couldn’t be happier with the purchase and I recommend this to anyone who doesn’t already have one!

great value makes my truck have a lil rumble to it

Easy instal. Sounds absolutely amazing. Looks bad ass. Solid build and more power.

El sonido del v8 en su maximo esplendor, es irresistible ir en carretera y no darle un aceleron solo para escuchar ese monstruo

2018 Silverado 1500 Custom Install was easy took 45mins has a nice deep rumble (super 40 exhaust no resonator) no more slow lag feeling when stepping on it as for gas mileage haven't noticed a difference. Only con is i would recommend a Aftermarket MAF sensor as the stock one isnt calibrated to allow that much air flow.

Excelente Kit, le quedo muy bien a mi Silverado 2014! Llego muy rápido, En excelentes condiciones. Fácil de Instalar! Excelente sonido del motor y un poco más de potencia!

Came very well packaged to prevent any shipping damage. Instructions are very easy to follow. I'm a mechanic and this is very simple for anyone with basic hand tools. Kit installed extremely well in 30 minutes. Looks great. Performs outstanding and now has no hesitation off the line. Makes the truck sound like a truck. I'm using the corsa exhaust and makes a perfect match.

Muy buen producto y me llego cuando se indicó,100%recomendado
