I bought it for looks here in the classifieds. My opinion is it does sound better and cleans up the look of the engine bay. Install on a 2016 was relatively easy. The Toyota clips you have to undo are the hardest part. On a good note, they tell you to dissect and free up the MAF wires so that they reach the new location on the CAi, you don’t have to do that much to make it reach, you can run the wire over the top of the air tube instead of the bottom. One important thing Toyota should make is a MAF sensor relocation wire, like an extension cord to make the install much quicker.
