I added this intake in hopes of some notable differences to my V6 Camry.
This intake definitely added some attitude to the sound of my Camry. It's kind of annoying at first, but I'm sure that it's because I was under the impression that I was driving a luxury vehicle. After a few days, I grew to love the sound. There is also a slight improvement in low end torque and the power band in the high rpm range. The mid-range torque and power is still lacking, but I'm sure a throttle body spacer and an exhaust system could tidy that up really quick.
As far as mpg's go, I was getting 28.5 mpg on the highway and I'm sitting at around 23.8 mpg in the city. Keep in mind that I typically have a heavy foot, even as a daily driver.
Overall, I'm impressed with the sound and noticeable power of the intake (being one of the first intakes on the market for this Toyota). I would not refrain from recommending this product to a friend, but I definitely would not try to entice him or her from putting this on their definite shopping list. This is why I'm giving it a 3 star rating. If you have the money, then yes, buy it and you will be satisfied. Although, if you're digging between the couch cushions or saving up for weeks to buy a product of this price, then I would suggest waiting.
