Love it! Install took roughly an hour. The hardest part was rounding up all the tools if you don't have very many variations of the "screwdriver." The filter came with a detailed diagram instruction packet and fits snug and perfect. After the install, I noticed the engine purr much nicer. I haven't seen a gas mileage effect just yet because the product was just installed and I've been pushing the truck slightly more that I normally do to listen to the sound. So far a great purchase for the truck and I would definitely do it over again if the truck needed another filter... but because it's a K&N, you'll never need another one!!!For anyone who needs assistance, I found a video on YouTube from K&N showing install process. It's really not hard at all and believe me, it makes the truck sound amazing from the front end.PROS:Great sounding growl from motorNot too hard to installLooks amazing under the hood without being too flashyMakes driving a little more funCONS:Did not see a MPG increaseSqueals at roughly 2,000 RPMPhotos on instructions hard to see

I love it 100%!!! Best unit on themarket for the price and the chrome looks great. The issue was the install. I have a brand new Tundra TRD and its black... so you know leaning over the truck was on the stressfull side :) It installed simple based on the part and directions but the fact it was my truck... you get the idea. Im a little concerned about the vacume line adapter, it seems a little brittle for a winter install, so i would wait till a warm day when you tighten it down. Other than that it looks great, sounds nice (no whistle) and seems to be great quality over all. I would buy again when i get another truck or car. Cant beat K&N, or the price Amazon charges!!!

Added 1 to 2 MPG, also give me greater performance off the line and on the highway!It does indeed make the vehicle louder, in a good way!Well worth the money.

Very impressed with the immediate horsepower gains as advertised. I was a little intimidated at first with amount of parts and hardware but the very clear and detailed instructions made it a breeze. I wish I'd bought this sooner because my 2012 Tundra 5.7L should have sounded this good long ago. Everything fit perfectly with only a slight trimming of the heat shield gasket. Very impressed by the results for a small amount of labor. Excellent product 👌

It takes a bit of time to install. I have been pretty consistent in measuring fuel economy in my mostly mixed/city driving. Prior to this intake I have done a lot of things to smoothe out the Sequoia and get optimal mpg including alignment, premium tires, high tire pressure, cleaning fuel system, new fuel pump and controller, Redline driveline fluids, Amsoil engine oil (10W30), new spark plugs, etc. Prior to the install I'd say I was at 14.1~14.3 mpg. The truck does not like to be below ~50mph or average economy starts to drop. After the install I'd say I am at 15.1~15.5 mpg and I can hold onto this average even with small town "light to light" driving mixed in there. This is NOT primarily highway driving, mind you. Anytime you install the MAF sensor into a different tube it can drastically change the performance of the sensor and they seemed to have found a good result for fuel economy.I do not care much about the power gains; they'll be minimal. The induction roar is surprisingly loud; I could take it or leave it. I did notice that the first time I started it it revved higher than normal and then cut out and died. I would say that (with the ECU reset) it definitely has higher flowing intake than the default expectation. It acted fine when I restarted it right after that.The factory intake box has extra screening in it for emissions and a "scouring pad" type of material glued onto the filter element to improve sound dampening. I previously removed these and it did help somewhat. Without them or with the K&N CAI you will get whistling sound at certain load from the engine. If you cannot tolerate ANY engine sound leave it stock.I am very happy with this product!

Installed in my son's 2018 5.7 Tundra. Sounds better, little more power, improved gas mileage.My son and I installed it in about an hour, and we don't have much as far as mechanical skills - if you can work a ratchet and screwdriver you can install it.

I wanted SO badly to like this. First off, it turns out it was missing the seal that goes around the filter box. But after installing, i Don’t see the purpose of the seal as it wouldn’t touch (or seal) from the engine area?The biggest issue I had was the noise it created in the cab of the truck. The intake noise sounded good but the system caused a VERY annoying high pitch whine in the initial RPM’s whenever you accelerate (at any speed). I thought this would be a simple fix but after a little research it appears this is inherent of K&N cold air intakes. What a shame....They REALLY should disclose this before the sale. Fortunately it’s a hassle free return with Amazon.

Some of the instructions were off regarding the mounting points, so we just winged it and nailed it. Gas pedal definitely feels lighter and fuel economy change is more and more noticeable.Not sure about the sound everyone claims to hear but otherwise this does the trick.

Easy installations and love the performance and the sound of it. You’ll notice the difference when it comes to sounding.
