  • 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

  • Great upgrade and can be done yourself.
Style: Metal Intake
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.

  • Power increase for pennies on the dollar...
Style: Metal Intake
Easy installation! It took about 35 minutes to install the kit. The instructions were fairly clear. Only one minor issue with the ground cable attachment point, but that took just a second to figure out. The filter install was very straight forward. I had a pretty significant increase in torque or at least the "feel" I had behind the wheel. I didn't dyno my Tundra to know for sure, but I could very easily feel the difference. My MPG went up from about 12.5 ave to around 14.5 just around the city. Highway/freeway MPG is up to about 20.5 ave. I all I'm very satisfied with this product and would highly recommend it as a quick, fun install with some really great results in my trucks performance! Love the improved "throaty" SOUND! ... show more

  • Great product sounds good.
Style: Metal Intake
Good product, sounds great give a nice throaty growl under harder acceleration. I dont here the whistle like some consumers stated. I stall was simple, do not tighten the brackets down until you set the airbox in to ensure you can align the bolt holes. MPG's didnt increase all that much. Make sure you disconnect your negative battery terminal like it states. It will not reset to re compute your fuel air ratio. Over all was expecting more MPG's than .5-.75 but its a bolt on. ... show more

  • Perfect fit for my Tundra
Style: Metal Intake
I was hesitant on purchasing this item because of the thought of open air instead of closed box. Very nice product gives my Tundra the exact sound I was looking for not to loud like I use to like but growls if you want it. Not to much road noise at all. We pull a camper and it sounds great not to much but just enough. Easy to install and a perfect fit. ... show more

  • Big difference
Style: Metal Intake
If you have good exhaust flow (duals), then a KnN intake would definitely add more punch. It adds torque and top end to my Tundra. Smooth acceleration and better fuel economy. About 1.2 miles per gallon (estimation). Sounds great as well. Clean look, and easy to install. Took about 1.5 hours.

  • 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
