I feel like this is a product that works best when combined with other mods.Assuming you want more exhaust tone, let’s assume you have a catback of some sort. Most of us go with the TRD. But maybe you want more sound (both from the exhaust in the back and from the engine up front) and the TRD CAI costs too much at $400?In that case I think this is a perfect medium. If you look at the TRD CAI, it basically consists of straight tube from the stock airbox to your throttle body, an air filter, a less restrictive scoop in the fender well, and a pretty red TRD top for the airbox. The rest… is identical to your existing CAI in your truck. A tall price to pay, huh?While I will admit that since the upper red part of the TRD CAI is slightly taller than the stock one, it may (in theory) supply more air at a moment’s notice… but odds are those types of gains are only noticable on a dyno and will be in the single digit numbers at a very specific RPM at best.So why get this product? Okay, you got the TRD Cat back but you want just a little more. I recommend pairing this product with TRD Part #: PTR0334079, the “TRD Flow Accelerator” which basically opens up a wider opening in your fender to allow more air into the airbox. If you purchase this K&N product without that part, the K&N can only do as much work as it can with the air that it is given. So give it more air! You’re buying this because you want better sound, and that extra $15 I believe is how you get it. You can purchase it as a replacement part for less than $15 and have 1/3 of the $400 TRD CAI.As for the air filter… yes, this K&N kit does come with an air filter that allows for higher airflow than stock but if you put it on a dyno… again, you won’t notice a significant difference. But from the reading I’ve done, the K&N air filters achieve higher flow in part due to allowing more junk to pass through their filter. So if you really wanna do a TRD CAI on the cheap, throw a TRD filter in your airbox along with this K&N tube. You’ll get that sound to compliment your exhaust… but at a fraction of the price of the TRD version, while maintaining a high level of filtration. Don’t worry, you can still paint the stock airbox lid red if you wish.Pros:- TRD CAI at a fraction of the price- Uses stock airbox, just like the $400 TRD modelCons:- K&N filter doesn’t filter as much as the OEM Toyota filter or the TRD Filter… but that’s a cheap fix. Just use this with a TRD filter.- Would it kill K&N to give us a red coupling to connect to the airbox with? It would totally help justify the pricetag, while minimizing costs on their end. The TRD one is red and pretty, this one is black and black. Both achieve the same result… but the $400 TRD one is red. K&N could totally steal sales from TRD by making parts of this kit pretty too. Do any of us feel good after spending $200+ on a plastic tube? At least pretty it up pls.Other:- Works best with AT LEAST the TRD Flow Accelerator, which is just $15. For max effect pair it with a proper catback exhaust. On stock Tundra, don’t expect much. You’re replacing cheap parts with cheap parts. You get what you pay for. But combine this with a decent exhaust… you just saved $200 versus the TRD model and achieved virtually the same result.

I decided to go and buy this intake, I knew upfront that the intake wouldn’t really increase performance, most don’t. Sure it reduces air flow restrictions but doesn’t compress the air. It arrives in two days with prime, I go to install it, assembly of the heat shield and mounting points takes about 15 minutes longer than it should have. As a suggestion to K&N, please for the love of God, pre-organise the hardware into marked baggies or cardboard packs. Now on to installing the heat shield, the instructions have you mount the shield into the lower factory holes but say nothing of the side mounting bracket needing to share a hole on the inside of the fender which was nearly f’n impossible to get to, no mention in the instructions because unless you remove the plastic trim and panel between the hood and the wipers you DO NOT HAVE ENOUGH ROOM!!! Squeezing your head and a hand between the hood lift piston and the hood is not fun. So ease of install was poor just because of this one mounting point.That said, it makes my truck rumble with light throttle and absolutely ROAR under heavy throttle!! That alone was worth the price of the intake and the aggravation of the install! No check engine lights, no running oddly, just pure ROAR! Increased fuel economy isn’t expected when you have your foot on the floor all the time so I can’t speak for that yet!

The Cold Air Intake worked well for me on a heavily modded 2017 Tundra. With a 6” lift and 35s, it’s a lot to turn over. Also, I run a bully dog tune and have a winch bumper and winch so a hundred pounds or better additional weight on front of truck.Gas mileage jumped from 12.8 to 13.2 mpg (mainly highway driving with some city). The intake also allows the engine to maintain speed easier (I see less jumping around on the mpg view). Finally, it sounds great and throttle response is noticeably improved.

Fit great and was easy to install. My gas mileage also improved by more than 2 mpg just by adding this. Truck also sounds great.

Works as should, I get these for all my autos

Strange there no instructions included but easily found online. Love the new sound. Makes the exhaust sound deeper too.

2016 Tundra 5.7 along with the TRD air accelerator. Unknown on mileage yet. No sound on Induction which is disappointing

Once installed this works very well and I’m happy with it. The new growling sound it makes is crazy. I put one of these on my Civic SI earlier this year and was impressed with it then. In town I definitely no improvement in gas mileage but on the highway it seems to improve by more than 2 Mpg as I drive the same stretch of highway a lot.
