Review on 🚀 Airaid Cold Air Intake System: Enhanced Horsepower, Unmatched Filtration for 2007-2020 TOYOTA (Sequoia, Tundra)AIR-511-213 by Jason Childs

So far I'm really impressed. The instructions for removing the intake manifold and installing the Airaid system were very clear. Installation was very easy and took less than 1 hour (I'm honest about the mechanical stuff). I advise you to loosen all the clamps as much as you can to help with the installation and also heed their advice not to tighten the screws to the end. After installing it, I tried my Sequoia and was very surprised at how loud it sounded. There's a distinct growl at low speeds with a bit more acceleration than usual, but once you start moving it quiets down and sounds like a factory noise. Between 45 and 55 mph I noticed a bit of a high pitched tone that sounded pretty decent. If you go over 45 mph and really hit the gas the deep growl gets loud and sounds pretty sticky! I've also already noticed a significant increase in fuel economy per gallon; increased from about 12.9 mpg to about 13.9 mpg.
