K&N Cold Air Intake Kit: High Performance, Guaranteed To Increase Horsepower: Fits 2007-2008 Chevy/Gmc/Cadillac (Silverado 1500, Suburban, Tahoe, Avalanche, Sierra 1500/Denali, YUKon, Escalade)57-3058

Everything about the kit feels cheap and nasty, even the supplied hardware. Expected better from K&N.

Posted video also. dont mind my face i was looking at my phone because i thought it would drop while i was revving the engine lol. I placed it on top of the Cold Air Intake so you can hear it. If you have a subwoofer hooked up to your computer like i do, it sounds really good almost exact.I just got this CAI for my 2007 Silverado (NBS) and installed it the same day. Let me tell you if you are looking for a performance upgrade for your Truck. This is the way to go. at First i was looking at the 77 series, i believe it was the 77-3058 and did a little more research. The only real difference is the Chrome intake tube and a smaller gain of Horsepower than this product. On top of that the 77-3058 costs 30-40 dollars more(price referenced from Amazon). So if your looking for more on looks then probably the 77 would be better for you. Me personally i dont go around opening my hood in public showing off my engine, and i would rather go with the more horsepower with this. All that is said so far this CAI is amazing and it sounds really good with my Flowmaster Super 40 muffler. I am an amazon prime member and never wright reviews but i had to on this one. Anyways here are some things to take note of. Its not bad at allInstallation.Well it was really easy for me, im not a vehicle mechanic, but i have experience in replacing small parts in my truck like headlights,oil,tail lights, belt etc. just the basic stuff but I am a Apache helicopter mechanic for the US Army so i guess im used to it but if i have to rate the difficulty level on installation it would be really easy even for someone who is starting to do DIY stuff on their vehicle. The instructions that come with it are fairly easy to read. Its just the bolts and nuts thats hard to tell which one to use even though it is labeled in the instructions in weird names like "bolt1/4lock" something like that. I dont remember that stuff but i still figured it out. Its too easy. installation time for me was about 45mins. For a beginner maybe an hour and 30 mins tops. also comes with a heat shield/cover on the top.Performance.Increase Throttle response was really noticeable and it does not sound like your engine is struggling anymore because of the intake. I was surprised on this one, i drive mostly freeway and suburb type area not city and within a couple of days my MPG went from 17.3mpg to 19mpg. I have a V8 4.8L engine so results may vary on your driving and area. But man I tend to punch it at stop lights now haha. it sounds so good. another thing is it comes with a Million mile warranty and you would never have to replace your filter ever again, just clean it after the recommended amount of miles/months. 5/5Packaging.If you are getting this item from amazon then your item is secured. The product box was in a regular box. they opened the product box and stuffed it with some type of storopack. Everything came in undamaged and still in their plastic cover and the Filter was in its own box. 5/5Overall.HIGHLY RECOMMEND this product (K&N makes great reliable stuff)EASY installation.GREAT packaging from both AMAZON and K&N.If you have a question at all feel free to leave a comment and i will give you my email.

Initially had an engine light when I put this on, my fuel trim was +20. Turned out I forgot to hook up the crankcase vent tube that is on the side of the intake, engine light is gone and it runs like a dream.Thank you

Easy to install, definitely woke my suburban up. Much more responsive and it sounds great! Womp Womp!

Awesome product. shipping was quick, just as advertised. Just the only thing was that this product had 2 items missing. I called up K&N and they rectified the issue right away. 10/10 for customer service. the best part was they Fedex it to me and I got the missing items in 3days!!! must great. for the product it self decently increase horse power my truck sound GRRRRRREAT and there was a small increase in my fuel milage. defiantly recommend this product.

Although it's very easy and cheaper to go your local auto parts chain and put together your own intake, I'd rather spend the money for a K&N Kit that is already designed to fit and includes the ability to shut out the engines heat and have a cold air intake. Not to mention putting it on a newer vehice. Also for my set up it works great in conjunction with the stock free flow cat, and a Flowmaster Cat-back dual exhaust kit I installed. Adds more deeper rumble without having to get a different series muffler. And no need for a throttle body spacer, for the most part. Unless you are racing and need to get every little single HP or performance you can get.
