    • Great for the price

Great intake for my 2021 tundra I can hear and feel the difference and the sound it makes it’s amazing.

    • Makes her purr much nicer!!!
Style: Roto Molded
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 motor Not too hard to install Looks amazing under the hood without being too flashy Makes driving a little more fun CONS: Did not see a MPG increase Squeals at roughly 2,000 RPM Photos on instructions hard to see ... show more

    • Great upgrade and can be done yourself.
Style: Metal Intake
Review Image by chris
I bought and put this cool air intake in myself. Could feel the throttle response instantly. I never put one in before. Followed the instructions. Took a couple hours a rusted bolt broke. So I just replaced with a self tapping screw. I've put 5000 miles on it since I bought it. No engine problems and does help with the gas mileage. But it sounds awesome when you step on it.

    • Parts missing great sound once installed
Style: Roto Molded
Easy to install but there were 2 brackets missing in the box. I was able to fabricate my own but still hard to believe considering the brand. 4 stars because of this. The sound of the engine once installed is awesome though and it looks great!!! Took about 1.5 hrs to install due to the missing parts. ... show more

    • STRESSFULL!!!
Style: Metal Intake
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!!! ... show more

    • Don’t Buy/Missing Parts on Multiple Reorders
Style: Roto Molded
WHATEVER YOU DO - DO NOT BUY THIS KIT 12/12/2025 UPDATE - I bought this back in June and had return it first and get a replacement due to lack of parts…..then I had to get extra parts kits twice anyway from KN because they failed to send me the complete list. Today i Just went to finally install, 6 months later, and had two more critical bolts required. I had to go to Lowe’s to find something that would work because o wasn’t call KN a third time for parts - completely ridiculous. I have used K&N in the past but I have ordered this product multiple times and each time the kit was missing all of the accessory bolts, nuts and brackets. I have had to call K&N to get the parts sent to me. I got the box of replacement parts and it was missing several items so I still could not install it for a second time. I am waiting for the 2nd box of parts and it’s been 3 months since my last Amazon reorder. Unfortunately, K&N has a bad quality control problem with its assembly packaging and its customer service phone line. Will see how the 2nd shipment of replacement parts goes. ... show more

    • Wakes up the 5.7, but QC lacked on this one
Style: Metal Intake
Put this in an otherwise stock '21 Tundra. Definitely sounds more aggressive, still has that Tundra whistle though. I'm now reading that is a consequence of the design of the gasket between the throttle body and the engine. Either way, this did not fix that, but it is less noticeable with the increased sound of the engine. QC was pretty crap on the aluminum version I got. The mass flow sensor would not install because the hole in the adapter wasn't machined correctly and had metal in the way of its' install. I had to dremel it out to get it to work. That's really poor quality for something in this price range. Hence the 3 stars. Looks great once properly machined and installed. Has not caused any alarms, check engine lights, etc. ... show more
